How do I delete columns in a data table with their names containing "UL" or "LL" or "UCL" or "LCL" or "USL" or "LSL" and the column containing only "." (NOT empty)
I have a large dataset on hand and want to delete all columns whose name contain "UL" or "LL" or "UCL" or "LCL" or "USL" or "LSL" and the whole column only contains "." but not empty except the column name. (images are shown below) I did not know how to do this after searching Google and read the JMP manual. Thanks for help on this.
