Hello, I just switched from R 2.0.0 to R 2.0.1 on an altix system. The aafSymbol was working before I switched, but now I get the error > aafSymbol("1452220_at","moe430a") Error in unique(c(new, .Library)) : subscript out of bounds There is no problem when I use the hgu95av2 example > data(aafExpr) > probes <- geneNames(aafExpr) > symbols <- aafSymbol(probes,"hgu95av2") > show(symbols[6:10]) An object of class "aafList" [[1]] An object of class "aafSymbol" [1] "FGFR2" [[2]] An object of class "aafSymbol" [1] "IL18" [[3]] An object of class "aafSymbol" [1] "IFNB1" [[4]] An object of class "aafSymbol" [1] "RAB5B" [[5]] An object of class "aafSymbol" [1] "TAF11" and I do have the moe430a library loaded, so I'm not sure how to troubleshoot this. I am using version 1.0.11 of annaffy and version 1.6.5 of moe430a. Thanks, Jeff Graduate Student University of Minnesota [[alternative HTML version deleted]]
