[R] Accomplishing a loop on multiple columns

[iliketurtles]

Lists are the answer.


LIST<-list()
 for(i in 1:ncol(results6))
 {
  LIST[[i]]<-lm(results6[,i]~data$observed)
 }

You'll now have a 91 entry list of lm(). You can then do something like
this:

LIST2<-list()
 for(i in 1:length(LIST))
 {
  LIST2[[i]]<-LIST[[i]]$r.squared
 }

This should now be a list of 91 R-squared, which you can unlist() and save
in matrix form if you want.
