I agree that packages are using tcltk, but users do so at their peril. Just loading tcltk breaks multicore functions like mclapply. I don't understand why, you might be able to explain it to me. http://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15040 tcltk is discouraged, at least to some in R core. I would really appreciate some guidance on what graphics library I should use to develop GUI for R programs. There's no future in tcltk, apparently, but I don't know what to work with. pj pj > > There was recently an R bug report submitted that likely stemmed from > the user having such a build of R and recently there was also an R > help post that seemed to be related to this as well.
