Dear R user, I used from the library MASS the dataset cpus and the skript plot.tree.sequence.R, which are included in the tree package:>library(MASS) > data(cpus) > cpus.ltr <- tree(log10(perf) ~ syct + mmin + mmax + cach >+ + chmin + chmax, data=cpus)At home it works but at work I get this message:>Error in .C("BDRgrow1", as.double(X), as.double(unclass(Y)),as.double(w), : C/Fortran function name not in load table I do not understand this message and I would be very glad if someone could give me some advice. Since at home and at work I'm running R Version 90.1 with Win NT4 I was surprised to get the error message.

Then check if your MASS library is the latest one. After that everything should work.

Note that R 0.90.1 (note the number) is no longer supported on Windows: use at least rw1001 and update your libraries to match. -- Brian D.
