[R] Cannot install packages in R 2.12.0 on Windows 7

[Dick Beyer]

Hi,

I am unable to install packages on my R 2.12.0 Windows 7 machine. Here are the relevant lines:

sessionInfo()
R version 2.12.0 (2010-10-15)
Platform: x86_64-pc-mingw32/x64 (64-bit)

locale:
[1] LC_COLLATE=English_United States.1252  LC_CTYPE=English_United States.1252    LC_MONETARY=English_United States.1252
[4] LC_NUMERIC=C                           LC_TIME=English_United States.1252    

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

> source("http://www.bioconductor.org/biocLite.R")
BioC_mirror = http://www.bioconductor.org
Change using chooseBioCmirror().
> biocLite("Biobase")
Using R version 2.12.0, biocinstall version 2.7.4.
Installing Bioconductor version 2.7 packages:
[1] "Biobase"
Please wait...

Error: subscript out of bounds

7: .readPkgDesc(lib, fields)

5: getDependencies(pkgs, dependencies, available, lib)
4: .install.winbinary(pkgs = pkgs, lib = lib, contriburl = contriburl, 
       method = method, available = available, destdir = destdir, 
       dependencies = dependencies, libs_only = libs_only, ...)
3: install.packages(pkgs = pkgs, repos = repos, ...) at biocinstall.R#205
2: biocinstall(pkgs = pkgs, groupName = groupName, ...) at biocLite.R#5
1: biocLite("Biobase")


It doesn't matter if I use biocLite, or just install.packages(), I get the same error. I did a re-install of R, but that didn't help.  I'm hoping someone else has seen this error and might have a suggestion.

Thanks very much,
Dick
