Apparently the former, as I got the same error in R2.7.1 on Windows. 

Matbe relevant info(?):

[1] "i386-pc-mingw32"

[1] "i386"

[1] "mingw32"

[1] "i386, mingw32"

Subject: [R] Error: protect () : protection stack overflow

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

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