st: Finding all variables NOT containing a string
Hi Statasticians
I have a simple problem, but wasn't able to find the solution:
I want to
a) find all variables whose names do NOT contain a given string (say,
"tempsa")
b) have them stored in r(varlist)
Neither -describe-, -lookfor-, nor -ds- seem to be able to do the job. I've
looked on the web and found Fred Wolfe's -lfsum-, which finds variables
containing a given string with the possibility to exclude other strings. But
this command is unable to handle wildcards, so that I cannot list ALL
variables except for those containing the string "tempsa". (Also it does not
store its results in r(varlist)).
I hope and assume that some of you will immediately know the solution since
this must be a frequently encountered problem.
Best regards,
Alex
