Dear BioConductors, While trying to go over the demo data in the package Starr, I encountered this error message: > dataPath <- system.file("extdata", package = "Starr") > bpmapChr1 <- readBpmap(file.path(dataPath, "Scerevisiae_tlg_chr1.bpmap")) > cels <- c(file.path(dataPath, "Rpb3_IP_chr1.cel"), file.path(dataPath, "wt_IP_chr1.cel"), file.path(dataPath, "Rpb3_IP2_chr1.cel")) > names <- c("rpb3_1", "wt_1", "rpb3_2") > type <- c("IP", "CONTROL", "IP") > rpb3Chr1 <- readCelFile(bpmapChr1, cels, names, type, featureData = T, log.it = T) Error: could not find function "readCelFile" > sessionInfo() R version 2.12.2 (2011-02-25) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) locale: [1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] grid stats graphics grDevices utils datasets methods base other attached packages: [1] affxparser_1.22.1 affy_1.28.0 Ringo_1.14.0 Matrix_0.999375-46 lattice_0.19-13 limma_3.6.9 RColorBrewer_1.0-2 Biobase_2.10.0 [9] R.utils_1.5.7 R.oo_1.7.4 R.methodsS3_1.2.1 loaded via a namespace (and not attached): [1] affyio_1.18.0 annotate_1.28.1 AnnotationDbi_1.12.0 DBI_0.2-5 genefilter_1.32.0 preprocessCore_1.12.0 RSQLite_0.9-3 [8] splines_2.12.2 survival_2.36-1 tools_2.12.2 xtable_1.5-6 Any help? Can it be an issue of R version so the Starr should be used in in R Devel? Best, Yongde

Hi Yongde -- 'Starr' is not listed as 'other attached packages' so I think you're missing a library(Starr) The usual advice is to use a current R (2.13) and associated Bioconductor packages.
