RE: st: Changing the suffix on variable names |

Assume that you didn't know about -renvars- from Stata Journal, as just publicised by Martin Weiss. You could still slim this down and speed this up: 1. There is no need to push the wildcard varlist *_56epi through -ds- and then push its result r(varlist) into a local. This is repackaging the same information in three forms; one is enough. 2. There is no need for the family of middle macros y_`x' inside the loop. Thus this example can be slimmed to: clear set obs 1000 g abc_56epi=0 g def_56epi=0 g ghi_56epi=0 foreach x of var *_56epi { rename `x' `= regexr("`x'", "_56epi", "_45epi")' } Nick n.j.cox@durham.ac.uk Tirthankar Chakravarty Here is another, clunkier, option: /* Begin */ clear set obs 1000 g abc_56epi=0 g def_56epi=0 g ghi_56epi=0 ds *_56epi local varlist=r(varlist) foreach x of local varlist { local y_`x' = regexr("`x'", "_56epi", "_45epi") rename `x' `y_`x'' } /* End */ T On Fri, May 1, 2009 at 11:57 AM, sdm1 <sdm1@york.ac.uk> wrote: > I have 150 variables all with the same suffix.
