Others have answered the question that you asked (it is also a variation of Faq 7.21), but here is an answer to the question that you should have asked:
When working with datasets like this, it is better to create a list rather than separate objects with names like dat1, dat2, etc. For example: > mydat <- list(dat1=rnorm(10), dat2=rnorm(25), dat3=runif(100)) Now your loop can be: > for(i in 1:3) cat( sd( mydat[[i]] ) ) Or even simpler: > sapply( mydat, sd ) And when you are through with the data, you only need to delete one object, or copy one object, or save one object, etc. Hope this helps, > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > project.org] On Behalf Of Megh Dal > Sent: Wednesday, September 17, 2008 5:51 AM > To: [EMAIL PROTECTED] > Subject: [R] Loop on vector name > > [My previous message rejected, therefore I am sending same one with > some modification] > > I have 3 vectors with object name : dat1, dat2, dat3 > > Now I want to create a loop, like : > > for (i in 1:3) > { > cat(sd(dati)) > } > > How I can do this in R? > > Regards, > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting- > guide.html > and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
