Hi, I seem to have buggered my windows box in such a way that R CMD INSTALL no longer works, and I can't figure out what is wrong (and Google doesn't seem to be my friend either...). When installing a package (doesn't matter what package), I get the following error. installing to 'c:/R-2.5.1/library' ---------- Making package hthgu133aprobe ------------ adding build stamp to DESCRIPTION installing R files installing data files rm: failed to get attributes of `/': No such file or directory make[2]: *** [c:/R-2.5.1/library/hthgu133aprobe/data] Error 1 make[1]: *** [all] Error 2 make: *** [pkg-hthgu133aprobe] Error 2 *** Installation of hthgu133aprobe failed *** Removing 'c:/R-2.5.1/library/hthgu133aprobe' I'm using the R tools installed via the Rtools.exe installer, have the Path variable set up correctly, and I don't have Cygwin installed. Any suggestions? Best, Jim -- James W. MacDonald, M.S. Biostatistician Affymetrix and cDNA Microarray Core University of Michigan Cancer Center 1500 E.
