Hello Jim,
First, thank you for responding.
Indeed, the issue is the request to generate a personal library.
I use a wide variety of Bioconductor packages, from the most canonical
ones like ShortRead to more obscure ones like cosmo, however, no
function ever asked me to create a personal library as a condition for
execution.
Do you regularly encounter functions that make such demand? I am curious.
Hi, Ivan.
This request is from R, itself, and not from the affy package or any other
Actually, rma needs the cdf package corresponding to the chip, and calls
getCdfInfo and eventually cdfFromBioC if it is not installed. This is
apparently determined by getOption("BioC")$affy$probesloc, but this is
not well-documented (which is an understatment). A work-around would
make sure the package (from annotation(Data)) is installed before
calling rma(), and then you'd at least have more control over what to do
if prompted.
just.rma is a (much) more memory efficient approach if the goal is to
arrive directly at an ExpressionSet without needing the AffyBatch.

package. If you haven't seen this before, it was probably because a user
Library existed previously (you are asked only the first time it is needed)
or because the default system package location was writeable by you. See
the R manuals for details on library locations if you want more detail.

Thank you,
Ivan
PS: By the way, cosmo rocks.

There seems to be a dependency error that comes up when running an

Is this error reproducible by others?
I don't see an error here. But perhaps you are referring to the warning?
I'm not sure how it could be made clearer, however. The gist is that you
are
running R as non-root (as you should), and therefore don't have write
access
to the /usr/local/lib64/R/library, (which you should not), so R is
stating
that fact and asking you if you want it to create a personal library in
your
home directory, where in future it will look for any packages that aren't
found in the 'usual' place.
So, long story short, if you had simply typed a 'y' after that warning,
you
would have got the package downloaded and gone about your business.
Best,
Jim
Thank you
Ivan
