[BioC] variable "ygs98cdfSYMBOL" was not found

[Shawn Hoon]

Hello!

    I'm new to bioconductor and am trying to use the simpleaffy package.
My example is simple:

 >library(simpleaffy)
 >library(ygs98cdf)
 > x <-read.affy()
 > x.rma<-call.exprs(x,"rma")
Background correcting
Normalizing
Calculating Expression
pw<-pairwise.comparison
 > pw<-pairwise.comparison(x.rma,"treatment",c("n","a"))
 > pw.filtered<-pairwise.filter(pw)
 > summary<-results.summary(pw.filtered,'ygs98cdf')
Error in get(x, envir, mode, inherits) : variable "ygs98cdfSYMBOL" was 
not found

Any ideas?

Apologies if this is the wrong list for this mail.

cheers,

shawn
