What does the choose function mean?
In Excel, the choose function was a function that was used to select and return a value from a list of parameters. Its grammar is Choose(index_num, value1, (value2),...), The index_nam is a necessary argument. It is a numerical expression or field. The result of the calculation should be a number between 1 and 254, or a reference to a cell containing a number between 1 and 254. The value1 is required, and the subsequent values are also available. The number of these value parameters is between 1 and 254. The function chooses a value or an operation to be performed from these value parameters based on index_num. The parameters can be numbers, cell references, defined names, formulas, functions, or text. If index_numis 1, the function CHOOSE returns value1; if index_numis 2, the function CHOOSE returns value2, and so on. If index_nums is less than 1 or greater than the sequence number of the last value in the list, the function Choose returns the error value #Worth!. If index_numis a decimal number, it will be rounded off before being used. If index_numis an array, then every value will be calculated when calculating the function, and the numerical parameters of the function can not only be a single value, but also a region reference.

The choose function failed.
There were several possible reasons for the failure of the Choice function: ** 1. Problem with parameters ** 1. ** Index_num-related ** - ** Out of range **: - Index_nam must be a number between 1 and 254, or a formula or cell reference that contains a number between 1 and 254. If index_nums is less than 1 or greater than the index number of the last value in the list, the Choise function will return #DOWN! Wrong value. For example, if you have a function with only three value parameters (value1, value2, value3), and you set index_nam to 4, the function will fail. - ** Minor Number **: - If index_numis a decimal number, it will be rounded off before being used. However, if an unexpected decimal result occurs during the calculation process, causing the index value to not meet expectations after the interception, it may also make the function seem invalid. 2. **Value parameters ** - ** Data type does not match **: - value1, value2,... These parameters can be numbers, cell references, defined names, formulas, functions, or text. If the data types of these parameters are not consistent with the expected data types during use, the function may not be executed correctly. For example, in a scenario where a value is selected based on an index number, if a value argument is accidentally set to text instead of a number, it may cause an error in the calculation. ** 2. Function nesting and combination problems (if there is nesting)** 1. ** Nested function error **: - If the Choose function was used in conjunction with other functions such as vlook up, sum, match, and so on, the error in the nesting function might cause the Choose function to fail. For example, when nesting with the Match function, if the look up_array of the Match function was set incorrectly and could not match the appropriate index value, then the index_nums passed to the Choose function would be wrong, causing the Choose function to fail. ** 3. Problem with the sheet itself ** 1. ** Data integrity **: - If the data that the function depends on is wrong or incomplete, such as the cell that is accidentally deleted or the data is mistakenly modified, the Choise function may not work properly. 2. ** Software-related issues **: - Sometimes, the Excel software itself might have a malfunction or version compatibility problem. Try to restart the Excel software or check if there is a software update that can solve this problem. "Choose" was equally exciting. Everyone was welcome to read it!
Use of the choose function
In Excel, the choose function was mainly used to select and return a value from a list of parameters. The grammar is Choose(index_num, value1, (value2),...). 1. ** Required parameters ** - **index_nums (required parameters)**: It is a numerical expression or field. The result should be a value between 1 and 254, or a formula or a reference to a cell containing a number between 1 and 254. If index_numis 1, the function returns value1; if index_numis 2, it returns value2, and so on. If index_nums is less than 1 or greater than the serial number of the last value in the list, the function returns the error value #DOWN!; If it was a small number, it would be rounded off before use. - **value1, value2,...**：Value1 is required, and subsequent values are available, ranging from 1 to 254. These parameters can be numbers, cell references, defined names, formulas, functions, or text. The function 'Choose', based on index_nums, chooses a value or an operation to be performed from these value parameters. If index_nam is an array, each value will be calculated when calculating the function. Moreover, the numerical parameters of the function could not only be a single value, but also a region reference. For example, the formula =SUM(ChoOSe(2,A1:A10,B1:B10,C1:C10)) is equivalent to =SUM(B1:B10). First, the reference B1:B10 returned by the ChoOSe function is calculated, and then the SUM function sums the values in the region B1:B10. 2. ** Usage scenario ** - ** Data column swap **: For example, in the formula =ChoOSe({1,2},B:B,A:A), you can swap the data of the two columns A and B. - ** Combined with Vlook up formula ** - ** Reverse Search Match **: The Vlook up formula can only search from left to right. If you want to search from right to left (for example, search for the employee number on the left by name), and the original data cannot be changed, you can use the choose function combination. For example, the formula =VLOOkUP(E2,ChoOSe({1,2},B:B,A:A),2,0). - ** Multi-criteria Match Search **: You can find a match based on two conditions without using auxiliary columns. For example, if you need to find a desired result based on two conditions, you can use the choose function formula combination. For example, the formula =VLOOkUP(E2&F2,ChoOSe({1,2},A:A&B:B,C:C),2,0).

choose function formula
In Excel, the basic grammar of the choose function was Choose(numerical number, first range, second range...). Its function was to select and return a value from the range list based on the number of values. For example, the formula =Choose(2,B2,B3,B4,B5), where "B2","B3","B4", and "B5" represented four regions. If the result of Choose was 2, which was the second region, then the final result would be the contents of cell B3. Index_numis a required argument. It can be a numerical expression or field. The result must be a number between 1 and 254, a reference to a cell containing a number between 1 and 254, or a formula. If Index_numis 1, the function "Choise" returns value1; if Index_numis 2, the function "Choise" returns value2, and so on. If Index_nums is less than 1 or greater than the sequence number of the last value in the list, the function Choose returns the error value #Worth!. If Index_numis a decimal number, it will be rounded off before use. Value1 is required, and the subsequent values are available. The number of these value parameters is between 1 and 254. The function Choise chooses a value or an operation to be performed from these value parameters based on Index_num. The parameters can be numbers, cell references, defined names, formulas, functions, or text. In addition, there are functions related to choose, such as ChooseCOLS, whose formula is = ChooseCOLS(Array, number 1, number 2...). The first argument is an array, followed by numbers, which means that the corresponding column number is extracted according to the number (For example, entering the formula =ChooseCOLS(A1:C8,1) will extract the first column result in the A1:C8 cells; entering the formula =ChooseCOLS(A1:C8,1,3) will extract the results of the first and third columns and then merge them together; if the number is filled in as a negative number, such as entering the formula =ChooseCOLS(A1:C8,-1,2),-1 means that the result of the first column is extracted from the right to the left).

choose function grammar
The choose function's grammar is "Choose"(index_num, value1, [value2],…). The index_nam is a required argument and is an integral number between 1 and 254.(It can be a numerical expression or the result of a field operation is a numerical value, or it can be a reference to a cell containing a number between 1 and 254, or a formula; if it is a decimal, it will be rounded off before use.). This value determines which of the values 1 and 2 will be returned by the function.(If index_numis 1, the function returns value1; if index_numis 2, it returns value2, and so on; if index_numis less than 1 or greater than the serial number of the last value in the list, it returns the error value #DOWN!). The value1 is required, and the subsequent values can be selected. The number of these value parameters is between 1 and 254. They can be numbers, cell references, defined names, formulas, functions, or text. "Choose" was equally exciting. Everyone was welcome to read it!
How to choose the TV function?
The choice of TV functions should be decided according to individual needs and preferences. First of all, he needed to be clear about his main purpose for using the television. If you were a movie fan and wanted a high-quality movie experience, you could choose a TV that supported 4K Ultra HD, a large screen, a borderless design, and a built-in sound system. If you like watching TV shows, the smart TV will become your good friend. You can choose a smart TV that supports various applications and voice control. In addition, some features could also be considered, such as support for HVR technology, high refresh rate, wide color range, and so on. Finally, don't forget to compare the functions and performance of different brands and choose the TV that suits you.
How to use the choose function
The basic grammar of the function is: Choose(index_num, value1, [value2],...). The index_nam is a required argument. It is an integral number that is used to specify which value argument to select. Its value starts from 1. For example, if there are 5 values in the list, the valid range of index_numis 1 to 5. If index_nums is less than 1 or greater than the index number of the last value in the list, then CHOOSE returns #OUT! Wrong value; if index_nam is a decimal, it will be rounded off before use. Value1 is required, and the subsequent values are available. There are a total of 1 to 254 numerical parameters. According to index_nums, Choosewill select a value or an operation to be performed. The parameters can be numbers, cell references, defined names, formulas, functions, or text. For example, if the formula = CHOOSES (2,B2,B3,B4,B5), if "B2","B3","B4", and "B5" represent four regions, and the result is 2, that is, the second region is selected, and the return value is the contents of cell B3. The Choose function can also be used in conjunction with other functions, such as the Vlook up function to perform a reverse search: =VLOOkUP(E2, Choose({1,2},C:C,B:B),2,0); the Sum function to perform a column separation: =SUM(Choose({1,2,3},B:B,D:D,F:F)), etc. "Choose" was equally exciting.

How to use the choose function
The basic grammar of the function is: Choose(index_num, value1, [value2],...). 1. **index_number (Required)** - This is an entire number, and its value starts from 1. It is used to specify which value to choose. If there are 5 values in the list, the valid range of index_nam is 1 to 5. If index_nums is less than 1 or greater than the index number of the last value in the list, then CHOOSE returns #OUT! Wrong value; if index_nam is a decimal, it will be rounded off before use. For example, when index_numis 4, the function will return the value4; when index_numis 4.6, the function will still return the value4. 2. **value1, [value2],... (Value)** - Value1 is required, and subsequent values are available. There can be 1 to 254 numerical parameters. These parameters can be numbers, cell references, defined names, formulas, functions, or text. Choose will choose a value or an operation to perform based on index_num. However, unless the choose function is used as an array, it is not recommended to use a cell range for value. The following are some examples of specific applications: - ** Basic Usage **: For example, the formula = CHOOSES (2,B2,B3,B4,B5). Here, it is assumed that "B2","B3","B4", and "B5" represent four regions or values respectively. Since index_nam is 2, the returned value is the second region or value (this is the content of cell B3). - ** Reverse search with the VlookUp function **: When you need to find the corresponding amount based on the sales name, but the sales column you want to find is not in the first column of the search area, you can use the combination of the Choose function and the VLOOkUP function. For example,=VLOOkUP(E2,ChoOSe({1,2},C:C,B:B),2,0), ChoOSe({1,2},C:C,B:B) means to select the first region C:C, then select the second region B:B, and combine them into a search range. This can solve the reverse search problem. - ** Using the Sum function to calculate the sum across columns **: If you want to calculate the sum of all the products across columns, you can enter the function formula =SUM(Choise ({1,2,3},B:B,D:D,F:F)). First, select each column of the amount, and then use sum to calculate the sum. "Choose" was equally exciting. Everyone was welcome to read it!
Choose Function in R Language
In R, the choose function was a very basic and important function. Its purpose was to select one or more elements from a specified object and return them. In the R language, this function can select rows and columns of data from a matrix, a list, or a data frame. For example: - As for the selection of the elements of the matrix: create a matrix `a <- c(1,2,3,4)`. If `a(2)` is used, the second element 2 will be returned. If `a(c(1,3,4))` is used, the first, third, and fourth elements will be returned. - For the selection of matrix elements: create a matrix `b <- matrix(c(1,2,3,4,5,6),nrow = 2, ncor = 3)`, use `b(1,2)` to return element 2 in the first row and second column, use `b(,3)` to return all elements in the third column. - For the selection of data frame elements: create a data frame `c <- data.frame(name = c("John","Mike","Lily"),age = c(20,25,30))`, use `c(2,1)` to return the element Mike in the first column of the second row, use `c(,2)` to return all the elements in the second column (age column), use `c$name` to return all the elements in the name column.

How to use the table choose function
In a table (using Excel as an example), the grammar of the ChoOSe function is ChoOSe(index_num, value1, [value2],...). Its function was to select a value from a list of up to 254 values based on the index number. The following are some typical usages: ** 1. Transform date into quarter ** If column A is date data, to convert the date to the corresponding quarter, you can enter the formula in the corresponding cell (such as column B):= Choice (Month(A2),"1st quarter","1st quarter","1st quarter","2nd quarter","2nd quarter","3rd quarter","3rd quarter","4th quarter"). Take cell A2 as an example. Months (A2) will get the month number of the date in cell A2. This month number will be used as the index number, and the corresponding quarter string will be selected according to the settings in the formula. ** 2. Replacing the nesting of the IF function to determine the level ** If there is a comparison table of scores and grades (such as cells E1:F6), to determine the score level of each student in column A (the results are placed in column C), you can enter the formula in cell C2:=Choose((B2>=0)+(B2>=60)+(B2>=70)+(B2>=80)+(B2>=90),"E","D","C","B","A"). In this formula, the calculation result of (B2>=0)+(B2>=60)+(B2>=70)+(B2>=80)+(B2>=90) was used as the index number, and the corresponding level was selected according to the range of conditions that the score met. ** 3. Reverse query with the VLOOkUP function ** For example, if there was an employee information table A1:D8, one had to inquire about the employee number of a specified employee. You can enter the formula in the corresponding cell (such as G2):=VLOOkUP(F2,Choose({1,2},$B$1:$B$8,$A$1:$A$8),2,False). Here, Choise ({1,2},$B$1:$B$8,$A$1:$A$8) will generate a new array, with the B1:B8 "Name" column as the first column, and the A1:A8 "Work Number" column as the second column. Then the VLOOkUP function will use this new array as the search area to perform a reverse query. ** 4. Randomly select data from a specified range ** If you want to randomly select a name from the names in cells A2:A5, you can enter the formula in cell C2:=Choose(Randbeteen (1,4),A2,A3,A4,A5). Among them, Ran Between (1,4) would generate a random number between 1 and 4. This random number would be used as an index number to select a name from A2, A3, A4, and A5. In addition, you can also use the choose function to achieve the sum of the conditions of the region, or when you use the vlook up function to search for data and the search area is inconsistent with the usual search area, you can use the choose function to re-match the area to be found for reverse query and other operations.
