As far as I know, the problems with running 64-bit R on windows are due to the lack of a well-developed, 64 bit minGW compiler. Therefore I would imagine that the packages that may have trouble installing under the experimental 64 bit build are those that include either C or Fortran source code that needs to be compiled. You may also find that you need to compile packages yourself-- prebuilt 64 bit versions for windows may not be available on CRAN. Axel Urbiz wrote: > > 2) MacOS or Unix.

I personally use 64 bit R on Mac OS and have had no problems developing and installing packages for the 64 bit system. -Charlie -- View this message in context: http://n4.nabble.com/R-on-64-Bit-tp1563895p1564056.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
