[R] Problem with pixmap on R 1.7.0?

[Kenneth Cabrera]

Hi R users:
I got the following message when I use the pixmap library
on R 1.7.0 over w2K platform (on R 1.6.2 it runs right).

pixmapGrey(matrix(c(0,1),128,128))
Error in .class1(object) : Object "from" not found

I download the library .zip file from:

http://cran.r-project.org/bin/windows/contrib/1.7/pixmap_0.3-2.zip

Other question:

When I try to "Install package(s) from bioconductor" I got the
following message:

local({a<-CRAN.packages(CRAN=getOption("BIOC"))
+ install.packages(select.list(a[,1],,TRUE), .libPaths()[1], available=a, 
CRAN=getOption("BIOC"))})

trying URL `http://www.bioconductor.org/bin/windows/contrib/1.7/PACKAGES'
Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"),  : 
cannot open: HTTP status was `404 Not Found'

Are the packages in other path of www.bioconductor.org? Which one?

Thank you for your help.

Kenneth
