OK, part II of this process and once again, let me start by saying
that I
am sorry to bother you with such an irrelevant question and I
understand if
you can't reply to it
I am biologist working on microarrays (Affy) and I am trying to run R
(I
have some experience on S plus); I am using a Windows machine and
Windowns
2000 as operative system
I am using the affy library and trying to read some Drosophila files
I tryed to install the correct environment but just can't do it
I have read the manual and althought I have tried all the functions
mentioned there the error cames always the same:
Error in as.environment(get(object@cdfName, inherits = FALSE, envir =
where)) :
Invalid object for as.environment
on the manual it looks really simple: one just has to download and
install
the cdf environment
I downloaded ok, but as for installing it, I just don't know how to do
it!

Hmm, the link seems dead. I'll ask Stefano (who I believe submitted
it).
Hi,
I am trying to use bioconductor to analyse microarray. Somehow my
affy
package was not functioning properly today. So I unstalled R and
reinstalled it again. But I cannot seem to install bioconductor. when
I
run getBioC(libName = "all"), I am getting the following message
Error in getBioC(libName = "all") : Directory R:/libraries/gm does not
seem to exist.
Please check your 'destdir' parameter and try again.
Please help me if you can.

The 'destdir' parameter defines where the packages get installed to.
The
default is '.libPaths()[1]' (which is generally going to be
'<path-to-r>/library').
getBioC() checks to see if this directory exists using the call:
file.access(destdir,mode=0)
If that returns a negative value, it complains that the destdir
directory
does not exist and halts. So the first thing to check is if
'R:/libraries/gm'
actually does exist on your system ...
