Description

This X-Function takes a cell or column of delimited values and parses them to new columns.

Examples

This example imports an ASCII file containing categorical data, uses the catrows()$ function to obtain row indices for each category, then outputs those row indices to new columns. The resulting sheet text2cols lists row indices for each category. 

// create an empty book and import the file automobile.dat into the new book
newbook; string fname$= system.path.program$ + "Samples\Statistics\automobile.dat";
impASC;
// set column 2 as categorical and sort it in ascending order
wks.col2.categorical.type=2;
wks.col2.categorical.sort=1;
// get column 2 into range variable rA
range rA = [automobile]automobile!"Make";
// create a new book and use category function to copy categories in rA to column A of newbook
// to column B, add row indices of occurrence for each category, as a pipe-separated list 
newbook;
col(A)=category(rA)$;
col(B)=catrows(rA)$;
// taking pipe-separated strings in [Book2]Sheet1!B as input, output values to new sheet in <input>.
text2cols ix:=[Book2]Sheet1!B delimiter:=pipe nosplit:=1 other:=[Book2]Sheet1!A;
