I need to pick your brain again:
Take this picture alone.The red box is where the number of columns is variable.
For the convenience of description, column 4 is used as the Group.
Column variables starting and ending in column 5 are the values requiring Summary.
How are the column names in the red boxes represented in the form of variables?
dt = Open( "$SAMPLE_DATA/Boston Housing.jmp" );
I can only do variable form in this way at the moment.Thank you!
