Hi all, This is more or less a FYI: I ran into an error when trying to use duplicateCorrelation in limma along the lines of: function "mixedModel2Fit" not found (I didn't keep the exact text). This function didn't seem to be in limma, but since duplicateCorrelation called for package statmod, I checked it. However, it wasn't in the statmod 1.2.0 that I had gotten in the middle of October. I checked CRAN and saw that there was a new version of statmod 1.2.3 put up on Dec. 12. I updated statmod and it did have mixedModel2Fit. There hasn't been anything about this on Bioconductor, so I thought I put out a warning in case anyone else runs into the same problem and (hopefully) searches the archives... Here's my sessionInfo (only statmod was changed): R version 2.2.0, 2005-10-06, i386-pc-mingw32 attached base packages: [1] "tools" "methods" "stats" "graphics" "grDevices" "utils" [7] "datasets" "base" other attached packages: RWinEdt affyPLM affydata limma gcrma matchprobes "1.7-3" "1.6.0" "1.6.0" "2.4.4" "2.2.0" "1.2.1" affy Biobase statmod "1.8.1" "1.8.0" "1.2.3" > Cheers, Jenny Jenny Drnevich, Ph.D. Functional Genomics Bioinformatics Specialist W.M.
