[R] pb with install

[Ghislaine Guigon]

dear all,

I try to update my Rversion fro 1.7.1 to 1.8.1 on linux. I have a problem 
when I try to install pacakges from Bioconductors with :

source("http://www.bioconductor.org/getBioC.R")
and
        getBioC(relLevel="release")

somme errors append and when I make a library(affy) for example I obtain :

 > library(affy)
Error in setIs("character", "characterORMIAME", where = where) :
         Class "character" is sealed; new superclasses can not be defined, 
except by setClassUnion
Error in setIs("character", "characterORMIAME", where = where) :
         Class "character" is sealed; new superclasses can not be defined, 
except by setClassUnion
Error in getClass(Class, where = topenv(parent.frame())) :
         "MIAME" is not a defined class
Error in library(affy) : .First.lib failed

Is someone still have this problem ?
