i m not sure what u really want to do but if ur looking for some subsample of dataset then u might wanna try this (say in case u want to resample ur dataset by column "id" in ur dataset then do
resample<-sample(dataset$id,n,replace=F) dataset<-dataset[resample, ] note here n is the size of subset u wanna sample from ur dataset hope this helps. cheers tasneem zaihra On Tue, 1 Apr 2008 14:23:10 -0400 "Georg Ehret" wrote: > Dear R community, I am using a dataset and would like to define new > variables using a R variable: > > e.g. > > for (i in 1:10){ > dataset$i<-something > } > > But this is not the right way, I get only one variable in "dataset"... > How can I change this? > > Thank you! > Georg. > ************************ > Georg Ehret > Johns Hopkins > Baltimore, MD > > [[alternative HTML version deleted]] > > ______________________________________________ > 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.
