Thanks for the useful input! I'll definitively try that later on. Kind regards, Andrea On Jul 21, 2008, at 5:57 PM, Austin Nichols wrote:

Andrea Bennett <mac.stata@gmail.com>: Sorry... -xi- and -xi3- don't allow you to automatically create nice labels. But it's easy to make your own program that does: open xi.ado in your favorite text editor, make two small changes, and save as a renamed file elsewhere, e.g. findfile xi.ado doedit `r(fn)' Now change label var `svn'`k' "`vn'==`value'" to label var `svn'`k' "`: label (`vn') `value''" and change program define xi to program define xil and save as xil.ado in `c(sysdir_personal)' then try running clear all sysuse auto la val rep78 rep78 la def rep78 1 ", Worst Repair Record", modify la def rep78 2 ", Poor Worst Repair Record", modify la def rep78 3 ", Fair Repair Record", modify la def rep78 4 ", Good Repair Record", modify la def rep78 5 ", Best Repair Record", modify egen ok=group(for rep78), label xil i.ok This approach uses the value labels of a categorical var to create nice labels for dummies downstream. If all you want to do is label vars created from the product of two vars, it's as simple as sysuse auto, clear g wl=weight*length la var wl "`: var label weight' * `: var label length' " d wl Now that I reread your post, though, after thinking through a different problem altogether than the one you wanted answered, I realize you want Stata to look through all var labels to find an instance of a variable name, and change all those labels at the same time it renames a var. So try prog relab version 8.2 syntax varname, to(string) loc f "`varlist'" foreach v of varlist _all { loc i "`: var label `v''" la var `v' "`=subinstr("`i'","`f'","`to'",.)'" } ren `f' `to' end sysuse auto, clear g wl=weight*length la var wl "weight * length" relab weight, to(height) Which renames and fixes labels simultaneously, but is not too smart about detecting potential mistakes you might make...

findit interaction

finds -xi- but not -xi3- for some reason. So see also -findit xi3-

Dear all,

I wonder if anyone knows a user written Stata command which allows one to

generate interaction terms, e.g. -female*age- or -female*group1-,

-female*group2- and -female*group3-, so that the labels of each variable are

used for the interaction terms (e.g. "female * age", "female * social class

3").

I just fear that at the end of the day, I will want to rename a few

variables. If one could only rename one variable (the non- interacted) and

the rest would be automatically generated, that would take away some

replacing besides the fact that the do-file won't grow that much...

Looking forward to any inputs! Kind regards,

Andrea
