Dear group, I have code that creates a LumiBatch object from two matrices of data: lumiBatch <- new( "LumiBatch", exprs = signalRaw, se.exprs = beadSD ) This code refuses to work in R 2.9: Error in `sampleNames<-`(`*tmp*`, value = character(0)) : 'value' length (0) must equal sample number in AssayData (0) And I am unable to trace the source of the error. I've also tried setting up phenoData and featureData objects, to no avail. FYI, the following call works fine: lumiBatch <- new( "ExpressionSet", exprs = signalRaw, se.exprs = beadSD ) How can I fix this problem? And this is my session info: R version 2.9.2 (2009-08-24) i386-pc-mingw32 locale: LC_COLLATE=English_Canada.1252;LC_CTYPE=English_Canada.1252;LC_MONETAR Y=English_Canada.1252;LC_NUMERIC=C;LC_TIME=English_Canada.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] lumi_1.10.2 RSQLite_0.7-2 DBI_0.2-4 preprocessCore_1.6.0 mgcv_1.5-5 affy_1.22.1 [7] annotate_1.22.0 AnnotationDbi_1.6.1 Biobase_2.4.1 loaded via a namespace (and not attached): [1] affyio_1.12.0 grid_2.9.2 lattice_0.17-25 nlme_3.1-93 tools_2.9.2 xtable_1.5-5 Best, Michal

Hi Michal I just checked the code and figured out the problem. The reason is that Biobase made some changes recently, but I didn't modify my code accordingly. Now I have fixed the problem in the lumi Release version (1.12.1) and developing version (1.13.1). I may take several days before it is available. Also you need to updated your R to 2.10.0 if you install the lumi package using biocLite(). Thanks for reporting the problem.
