[BioC] questions about U133A cdf packages

[Wenlei Liu]

I'm trying to use the U133A spike-in data set (Latin square data) to do some analyses. However, I can not load the cel files into R. I installed HG-U133A_tag_CDF.zip in R using "install package from local zip file" option, but still got the following error message. Does anyone know what's wrong?

> install.packages("E:/data/Liu/microarray/U133/HG-U133A_tag_CDF.zip", .libPaths()[1], CRAN = NULL)
