[BioC] Error when running rma

[Min-Han Tan]

Good evening,

I am encountering problems running rma with a particular CEL file
(when included into a group of other CEL files). It does not appear
when operating on other CEL files independently.  All files are
hgu133plus2 chips. My setup: R 2.0.1 on Linux; latest version of affy
(not devel)

>abc<-ReadAffy()
>cc<-rma(abc)
Background correcting
Error in density (x, kernel = "epanechikov", n=2^14)
need at least 2 points to select a bandwidth automatically

Error also appears on justRMA. 

Would appreciate any pointers. 

Thanks!
