How did you try to install the .zip file? I just tried (same OS, same
Rver) using 'Install from local zip file...' and it worked fine.

Hi to all,
I've installed on my pc (win xp pro os) the last version of R (1.7.1)
and BioConductor 1.2.1 I'm tring to analyze a affy dataset made with
hgu133a chipset. When I enter the string "xyzRMA<-rma(xyx)" it returns
me this:

	Environment hgu133acdf is not available.
	This environment contains needed probe location information.
	We will try to download and install the hgu133acdf package.

	Note: No specified download type, defaulting to Win32 
	[1] "Attempting to download hgu133acdf from BIOCcdf/"
	Error in download.file(fileURL, destFile, mode = "wb", quiet =
TRUE, method = method) : 
        	unsupported URL scheme

I've tried also to manually download the hgu133acdf.zip and to install
it in R, but it gives me this output:

	Error in file(file, "r") : unable to open connection
	In addition: Warning messages: 
	1: error -1 in extracting from zip file 
	2: cannot open file `hgu133acdf/DESCRIPTION' 
What can I do?
Thankyou very much...
