Dear Abraham, If I follow correctly what you want to do, the following should do it:
> f <- factor(c(1, 1, 5, 5, 8, 8, 9, 9, 0, 0)) > f [1] 1 1 5 5 8 8 9 9 0 0 Levels: 0 1 5 8 9 > recode(f, " '1'=3; '5'=1; '0'=2; else=NA ") [1] 3 3 1 1 <NA> <NA> <NA> <NA> 2 2 Levels: 1 2 3 I think that your problem was that you didn't distinguish correctly between factor levels and their numeric encoding; factor levels should be quoted in recode(). I hope this helps, John -------------------------------- John Fox Senator William McMaster Professor of Social Statistics Department of Sociology McMaster University Hamilton, Ontario, Canada web: socserv.mcmaster.ca/jfox > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf Of Mathew, Abraham T > Sent: January-28-10 10:15 AM > To: r-help@r-project.org > Subject: [R] Recoding Variables in R > > > > VAR 980490 > > Some people have suggested placing new limits on foreign > > imports in order to protect American jobs.
