I am using 'simpleaffy' V 2.10 on Solaris R 2.0.1 and I get an error when running qc.affy

 > x
AffyBatch object
size of arrays=732x732 features (20935 kb)
cdf=Mouse430A_2 (22690 affyids)
number of samples=5
number of genes=22690

 > x.mas5

         22690 genes
         5 samples
                  phenoData object with 2 variables and 5 cases
                 sample: sample
                 treatment: treatment

 >qc <- qc(x,x.mas5)
Error in qc.affy(unnormalised, ...) : I'm sorry, I do not know about chip type: mouse430a2cdf

Even though I have installed mouse430a2cdf.

Thanks for any help in advance,
