Hi, First of all: thanks for providing this wonderful set of programs. I hope I'm not being too stupid with this question. I have R 1.9.0 installed on a Windows2000 machine. I installed BioConductor with >getBioC(relLevel="release") It seems to work fine. However, according to the documentation of getBioC, the installed default set should include the "affy" set, which in turn should include the "makecdfenv" package. However, makecdfenv doesn't seem to be installed (it is not there when looking at library(), library(makecdfenv) results in an error message, and I can't use make.cdf.package()). I've then tried >getBioC(libName="makecdfenv", bundle=FALSE) ... [1] "All requested packages are up to date" Warning message: 'package.description' is deprecated. I've also tried installing makecdfenv by hand, but failed... Thanks for your help, Martin -- _______________________________ Martin Lercher, Ph.D. Royal Society Research Fellow Dept. of Biology & Biochemistry University of Bath BA2 7AY, UK www.bath.ac.uk/bio-sci/lercher

Again, can you be more descriptive?
