Dear All,
Firstly, I am new to both R and bioconductor, but I have tried to
solve my problem with google, R FAQ and bioconductor help pages and
not got anywhere.
I have only installed R today, using this download
http://cran.ma.imperial.ac.uk/bin/macosx/
I'm trying to run the affy package to analyse some HG-U133A2 data....
and have come across an error:
"Error in R > eset <- mas5(Data) : object 'R' not found"
Whilst trying to work out why I get the above message, and what might
be missing I realise the following (from the sample workflow page):
"Affymetrix 3'-biased Arrays
affy, gcrma, affyPLM
Require cdf package, probe package and annotation package
All these packages are available from Bioconductor via biocLite()"
However when trying to install all three of these packages I get the
warning message
"package is not available (for R version 2.13.2)"
In the package list http://bioconductor.org/packages/release/bioc/
None of these three packages are listed for me to see if they run on
OSX.
Therefore I think I might be confused about these three packages and
the earlier error I received running affy.
Any clarification gratefully received.
Thanks in advance for your help.
Kind regards,
-Sarah
