dear r-experts: there is probably a very easy way to do it, but it eludes me right now. I have a large data frame with, say, 26 columns named "a" through "z". I would like to define "sets of regressors" from this data frame. something like
myregressors=c("b", "j", "x") lm( l ~ myregressors, data=... ) is the best way to create new data frames that contain all the variables I want, then use ".", and then destroy them again? or am I overlooking something obvious? sincerely, /iaw [[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.
