[BioC] bg.correct.gcrma?

[Ann Hess]

Is it possible to use the command bg.correct.gcrma in BioConductor 1.5 
with R 2.1?  I would like to examine the background corrected probe values 
using gcrma.  If this command doesn't work, is there something else that 
will allow me to perform just the gcrma backgound correction?  I found 
this command by searching the Bioconductor Mail archives (some correspondence
about bg.correct.gcrma appeared in 2003).  Even after loading affy
and gcrma, I can't find any information about the command bg.correct.gcrma...
