On a Windows XP (SP2) machine, when I use the package Affy (R 2.0.1, bioconductor 1.6),the following error message appears:


> library(affy)
> Data <- ReadAffy() 
> eset <- rma(Data)
Error in load(zfile, envir = envir) : ReadItem: unknown type 242
In addition: Warning message: 
package 'hgu133plus2cdf' was built under R version 2.9.0 
Error in library("hgu133plus2cdf", lib.loc = NULL) : 
        .First.lib failed for 'hgu133plus2cdf'


The reason why I use the old version of R is some functions whicn I saw in some books and manuals were not found in the latest version of R,such as "rowSds " and "heatmap ". I also can't find the download website of the package 'hgu133plus2cdf' built under R 2.0.1.

Does anyone can help me?

Thank you!
