Dear all, When running function 'testQAReport()', which uses function 'buildVignettes()' to create a pdf-file I get the following error: > source("testQAReport.R") > testQAReport() Error in .get_package_metadata(pkgdir) : Files 'DESCRIPTION' and 'DESCRIPTION.in' are missing. Since I did not get this error in earlier versions of R, could you

Dear all, I am currently analyzing a set of arrays hybe on the lattest affy Drosophila 2.0 GeneChip. I am trying to run simple annaffy analysis but can¹t find what is the name of the annotation file I need to use. Here is the output of the AffyBatch object I am using: > expData AffyBatch object size of arrays=732x732 features (16749 kb) cdf=Drosophila_2 (18952 affyids) number of samples=4

...Affymetrix expression array data * diagnostic plots and normalization for cDNA array data * storage and retrieval of large datasets * user interaction widgets * sequence analysis * proteomics There are currently 81 packages, not including precomputed annotation data packages for Affymetrix GeneChips(tm) and prepackaged general annotation databases such as KEGG, GO, and LocusLink.

Hi, all. I'm trying to cluster 12,500 objects using hclust from package mva. The distance matrix takes up nearly 600 MB. The distance matrix also needs to be copied when being passed to the fortran routine that actually does the clustering (it's modified during the clustering), so that's 1200 MB. I'm actually on a machine with 2.5 GB of memory (and nothing else running), so I

Hi-- While I agree that we cannot agree on the ideal algorithms, we should be taking practical steps to implement microarrays in the clinic. I think we can all agree that our algorithms have some degree of efficacy over and above conventional diagnostic techniques. If patients are dying from lack of diagnostic accuracy, I think we have to work hard to use this technology to help them, if we
