I am attempting to create a formula using as.formula for a PLS analysis.  I have used the code below successfully, but in a previous R version and with many fewer predictors.  Any help getting all of these predictors into one formula would be greatly appreciated.

TC.fmla <- as.formula(paste("TC ~ ", paste(vars, collapse= "+")))

As I mentioned, this code worked fine in a previous R version and with 2050 vars, however I now have the latest version of R and 36334 predictors in vars.

Do I simply have too many predictors for this to work, or is this an R 2.8.0 issue?
