Hello, 2 remarks: 1. Your current problem is that you CREATED the package, but did NOT install the package. Please read the R-admin guido on how to do this. 2. The Affymetrix CDF for hugene is NOT officially supported. It is not recommended to use it. Please read this: https://stat.ethz.ch/pipermail/bioc- devel/2007-October/001403.html Alternatively, you can use the MBNI Custom CDFs. My contribution on the custom CDFs is available via: http://nugo-r.bioinformatics.nl/NuGO_R.html Regards, Dr. Philip de Groot Ph.D. Bioinformatics Researcher Wageningen University / TIFN Nutrigenomics Consortium Nutrition, Metabolism & Genomics Group Division of Human Nutrition PO Box 8129, 6700 EV Wageningen Visiting Address: Erfelijkheidsleer: De Valk, Building 304 Dreijenweg 2, 6703 HA Wageningen Room: 0052a T: +31-317-485786 F: +31-317-483342 E-mail: Philip.deGroot at wur.nl <mailto:philip.degroot at="" wur.nl=""> Internet: http://www.nutrigenomicsconsortium.nl <http: www.nutrigenomicsconsortium.nl=""/> http://humannutrition.wur.nl <http: humannutrition.wur.nl=""/> https://madmax.bioinformatics.nl <https: madmax.bioinformatics.nl=""/> ________________________________ From: sneha patil [mailto:snp2312@gmail.com] Sent: Mon 29-3-2010 9:20 To: bioconductor at stat.math.ethz.ch Subject: [BioC] Fwd: regarding installaion of cdf package hiiii I have prepared a hugene10stv1 cdf package.I am facing problem in installing this package via R CMD INSTALL command.... so i created a cdf environment using the following command. > HuGene10stv1=make.cdf.env("HuGene-1_0-st-v1.cdf") Reading CDF file.
