[BioC] Problem with snprma

Dear Benilton,

I am trying to normalize a SNP type cell file with the oligo package.
But I obtain the following error with snprma:

> datos <- read.celfiles(list.celfiles())
Incompatible phenoData object. Created a new one.
Platform design info loaded.
> annotation(datos)
[1] "pd.mapping50k.hind240"
> preProc <- snprma(datos)
This may take a while.
Adjusting for sequence and fragment length......... done.
Normalizing...Error en sort(reference) : objeto "reference" no encontrado
Además: Warning messages:
1: there is no package called 'pd.mapping50k.hind240.crlmm.regions' in: 
library(package, lib.loc = lib.loc, character.only = TRUE, logical = 
TRUE,  2: data set 'pd.mapping50k.hind240Ref' not found in: data(list = 
paste(platform(oBatch), "Ref", sep = ""))

I had a glance to the function snprma() and I note that the default 
value for the "normalizeToHapmap" is TRUE and the reference object 
cannot be created.
Nevertheless, I guess that is not really the source of this error.
Please can help me to solve this problem.
best regards. Olivier
