Hi everyone, I have an array with a variable called comments. I wish to count the number of subjects whose post-experiment comments contain a string x and then cross tab this with other variables of interest, ex. age. Does anyone have any suggestions on how to count unique occurrences of a string embedded within a variable and cross-tab it with other variables?
I've looked through the help files, etc. One method I tried was to use strsplit to split comments. I can use this with table to count the number of occurrences of x, but I can't cross tab this with other variables because comments is a ragged array after being split.
