Hello all, R2.2.1, W2k I posted a similar question last week after having problem with a group update (using update.packages()), without getting any answer. Now I have updated all packages separately, and found that the problem comes from nlme: Everything comes home, the md5 checksums are ok, but then the old version can??t be removed from my computer, leaving a "nlme" library with

That's makes no sense. The automatic system we had generated an optimal dependency graph: no missing or unnecesary edg...

Hi, everyone, As you may know, NVIDIA has developed an open-source Fortran frontend for LLVM (http://flang-compiler.org), which consists of the flang frontend itself along with the corresponding Fortran runtime library. The existing frontend's code is mostly written in C, and while a production-quality implementation, does not follow modern software-engineering practices. Our long-standing
