Hey guys,
I've got a dataset full of employee information and I'm trying to add in a snapshot from earlier in the year. I typed mer 1:1 id using lastmonth.dta and first it told me it adjusted all the string lengths accordingly but then I got the error message _merge already defined. It did not go into the summary. I'd already merged in some other information about these people twice, so I figured I'd forgotten to drop _merge. But when I tried that it said _merge not found. Now I figure I just forgot something obvious, but I was wondering if this is an issue anyone else has seen?
