Hello, If I have two variables that are factors or characters and I want to create a new variable that is the combination of both what function can I use to accomplish this? Ex. Var1 Var2 SA100055113 19851113 And I want NewVar SA10005511319851113 Thanks in advance. Cameron Guenther, Ph.D. Associate Research Scientist FWC/FWRI, Marine Fisheries Research 100 8th Avenue S.E.

What does "combination of both" mean exactly. I can think of two interpretations that have two different answers. If you give a small example (as the posting guide suggests) it would certainly help me provide an answer. -- Bert Gunter Genentech Non-Clinical Statistics South San Francisco, CA> -----Original Message----- > From: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of > Guenther, Cameron > Sent: Wednesday, May 24, 2006 11:46 AM > To: r-help at stat.math.ethz.ch > Subject: [R] Joining variables > > Hello, > > If I have two variables that are factors or characters and I want to > create a new variable that is the combination of both what > function can > I use to accomplish this? > > Ex. > > Var1 Var2 > SA100055113 19851113 > > And I want > > NewVar > SA10005511319851113 > > Thanks in advance. > > Cameron Guenther, Ph.D. > Associate Research Scientist > FWC/FWRI, Marine Fisheries Research > 100 8th Avenue S.E. > St. Petersburg, FL 33701 > (727)896-8626 Ext. 4305 > cameron.guenther at myfwc.com > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! > http://www.R-project.org/posting-guide.html >
