Thanks for the help. I got the cdf file of the Arabidopsis ATH1 array (ATH1-121501.cdf) and tried to make the cdf package from it. I got the ath1121501cdf package by R, however, this package only contains folder data, R, man, and files DESCRIPTION, INDEX, TITLE, while the packages in the Bioconductor webpage contains a lot more folders. Below is how I did it in R. I am wondering what went wrong?? > make.cdf.env("ATH1-121501.cdf") Reading CDF file.

if you are using windows you need to get the tools to make window packages or contribute the package to bioconductor. they will do it for you. rafael On Mon, 3 Mar 2003, Hua Liu wrote: > Thanks for the help.
