Hi, I've downloaded R-2.6.2-win32.exe (base) from two CRAN sites (http://mirrors.ibiblio.org/pub/mirrors/CRAN/ and http://lib.stat.cmu.edu/R/CRAN/) and for both of those sites the expected MD5 hash is reported to be: ed512872818707f27ca05f08be7363c2 *R-2.6.2-win32.exe (See, for example, http://lib.stat.cmu.edu/R/CRAN/bin/windows/base/md5sum.txt). However, when I compute the MD5 hash (using two different MD5 hash generators) I get 4acf8298a829c2787b8fe848f866999a *R-2.6.2-win32.exe Could someone check and confirm that the MD5 sums on the CRAN server are incorrect? (And fix it?) Thanks, --Paul p.s. Given that two CRAN servers have the bad value, I'm guessing it's safe to install. It installed okay is seems to be running fine. -- Paul Lynch Aquilent, Inc.

I don't know what happened, but the version that was uploaded was shorter than the real one, which should have 30750532 bytes. The md5sum.txt file is correct for the real one, but doesn't match the truncated one. I've redone the upload, and now the md5sum matches. It will take some time for CRAN to synchronize with the change; it won't be immediately visible. But I also changed the page to say "Last change: 2008-02-09", so if you see that date, you should be getting the right download. I'll have to put some tests into the upload script. Duncan Murdoch

It installed okay is seems to be running fine.I've worked out what happened: there was a build of R-patched which overwrote the release, because it happened before the VERSION file had been updated to include "Patched". I don't upload md5sum.txt in the R-patched or R-devel scripts, so that's why you detected the difference. To confirm this, you could check the NEWS file: it contained entries for 2.6.2 Patched, as well as the 2.6.2 entries. As far as I know it's perfectly safe to use. Duncan Murdoch
