I agree with Nick and Joerg: preserving the variable labels doesn't make sense, given that the mapping isn't one-to-one. Nevertheless, I think I understand what you're trying to do. How about something like this? ********************************************************************************* clear input y id x2007 x2008 x2009 z2007 z2008 z2009 18 1 12 16 18 20 21 19 10 2 11 17 17 33 32 19 12 3 10 10 22 19 17 18 end // Labeling variables foreach v of varlist x* z* { label variable `v' "`=substr("`v'",1,1)' factor (`=substr("`v'",length("`v'")-3,4)')" } desc * // Looping over stems to capture variable labels foreach s in x z { local `s'label = subinstr("`: variable label `s'2007'", " (2007)", "", 1) } reshape long x z, i(id) j(year) // Looping over stems again to reinstate labels foreach s in x z { label variable `s' "``s'label'" } desc * ************************************************************************ Ryan On Wed, Dec 19, 2012 at 10:06 PM, Kieran McCaul <kieran.mccaul@uwa.edu.au> wrote: > ... > > > local vname: variable label campus80 > > reshape .... > > label variable campus "`vname'" > > > > > -----Original Message----- > From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of David Torres > Sent: Thursday, 20 December 2012 10:46 AM > To: statalist@hsphsun2.harvard.edu > Subject: RE: st: Preserve Variable Labels After Reshape > > Joerg, > > What I mean to preserve is the description of the variable stub, in your example the x. x1 and x2 could both, for instance, be labeled as, let us say, "the x factor."

I want to simply keep that description, which I thought was called the variable label. > > From my own file: I have variables called campus08 campus09 campus10. The description for these variables is the same in all three years (the two-digit number after the variable stub): "Campus ID Where Student Attended School." When I reshape from wide to long, I now have one variable, campus, that has no description.

The labels are the same. I am simple trying to keep those labels after a reshape.
