Hi Bioconductors, Good news for 64-bit Windows users! Thanks to Arnaud Droit from Raphael Gottardo's lab (and to Brian Ripley and Uwe Ligges who provided essential information to help solving this issue), a 64-bit version of the GSL (GNU Scientific Library) is now installed on gewurz, our 64-bit Windows build machine. This means that 11 more Bioconductor packages are now available on Windows 64-bit (i.e. 360/389 packages vs 380/389 for 32-bit Windows): GLAD flowClust MotIV PICS rMAT affyILM snapCGH beadarraySNP flowMerge ITALICS MANOR Reminder: Windows 7 is 64-bit and both 32-bit R (available here http://cran.fhcrc.org/bin/windows/base/) and 64-bit R (available here http://cran.fhcrc.org/bin/windows64/base) run on that OS. If you don't know which one is for you, please read: http://cran.fhcrc.org/bin/windows/base/rw-FAQ.html#Should-I-run- 32_002dbit-or-64_002dbit-R_003f Cheers, H. -- Hervé Pagès Program in Computational Biology Division of Public Health Sciences Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N, M2-B876 P.O.
