Thanks, Jim. I tried some things but I was unsuccessful. Next I summarize the procedure of my trials:
 
1) I noticed that my mirror was different from yours (see below) so I changed it accordingly.
 
> library(BiocInstaller)
> biocinstallRepos()
                                               BioCsoft 
           "http://bioconductor.org/packages/2.11/bioc" 
                                                BioCann 
"http://bioconductor.org/packages/2.11/data/annotation" 
                                                BioCexp 
"http://bioconductor.org/packages/2.11/data/experiment" 
                                              BioCextra 
          "http://bioconductor.org/packages/2.11/extra" 
                                                   CRAN 
                         "http://cran.cnr.Berkeley.edu <http://cran.cnr.berkeley.edu/> " 
                                              CRANextra 
                   "http://www.stats.ox.ac.uk/pub/RWin" 
                                                   MBNI 
            "http://brainarray.mbni.med.umich.edu/bioc" 

 
 
2) I relaunched a new R session, re-installed 'oligo' and tried again.
 
3) I re-installed R from the Seattle CRAN (http://cran.fhcrc.org), removed the affxparser folder, re-installed 'oligo' and tried again.
 
4) I installed R and all the required stuff in another PC computer, just to rule out I'm experiencing some weird compatibility issue in my own computer, without success.
 
Any suggestions?
 
Regards,
 
Luis
