[BioC] Unable to use GEOquery

[Juan C Oliveros Collazos]

Hi all,

I just downloadad and installed the package "GEOquery" from bioconductor 
web site. The installation carried-out with no errors.

However, when I try to load the library: "library(GEOquery)", I get the 
following error:

-------------------------------------------------------------------------
 > library(GEOquery);
Error in makeClassRepresentation(Class, properties, superClasses, 
prototype,  :
   element 2 is empty;
    the part of the args list of 'list' being evaluated was:
    (header = list(), )
Error : unable to load R code in package 'GEOquery'
Error: package/namespace load failed for 'GEOquery'
------------------------------------------------------------------------


This is the sessionInfo() output:
------------------------------------------------------------------------
 > sessionInfo();

attached base packages:

other attached packages:
[1] Biobase_1.16.1 limma_2.12.0

loaded via a namespace (and not attached):
[1] rcompgen_0.1-15
----------------------------------------------------------------------

Looking at this output, It seems that the package is not installed. 
However, when i do "installed.packages()" GEOquery appears in the list!

I can not figure-out where the error is...

Any help?

Thanks in advance!

Best,

Juan Carlos
