Wish: keep names in mapply() result
Hello! I have noticed that mapply() drops names in R 2.3.1 as well as in r-devel. Here is a simple example: l <- list(a=1, b=2) k <- list(1) mapply(FUN="+", l, k) [1] 2 3 mapply(FUN="+", l, k, SIMPLIFY=FALSE) [[1]] [1] 2 [[2]] [1] 3 Help page does not indicate that this should happen. Argument USE.NAMES does not have any effect here as it used only in a bit special

F90
Hello! Has anyone successfully compiled F90 sources in R-package? I found the same question on r-devel list from 2002 and I wonder if there is any progress. I heard that g95 and gfortran can be usable. And one more thing. I have a program written in F90 and lets suppose that compiler is not a problem. I've read manual 'Writing R Extensions' and successfully loaded one F77 subroutine

How long is winepath available?
Hello! Can someone provide me an estimate or relevant source of information on how long is command winepath available or from wich version of wine? I would need this as I work on some R[1] package R2WinBUGS[2] that calls a Windows program WinBUGS[3] and that program needs windows paths. Currently winepath or parsing of .wine/config is used and I wonder if I can remove fiddling with .wine/.config.

Hello! New version of R has came out and I would like to thank to all developers on this matter. So I should probably upgrade. Fine and no problem.
