[Bioc-devel] SnpFeatureSet validity error in oligo

I don't know if this is a question for Benilton or Martin Morgan (or
someone else?). Anyway, I am getting an error when I try to create a
SnpFeatureSet with some Affy SNP array data. Following is the code and
error:

dat <- read.celfiles(filenames=list.celfiles())

Incompatible phenoData object. Created a new one.
Loading pdmapping50kxba240
Package loaded.
Error in if (!all(featureNames(assayData(object)) ==
featureNames(object))) msg <- paste(msg,  :
	missing value where TRUE/FALSE needed
