Hello All, I'd like to use gammaFitEM(), methylationCall(), and lumiMethyStatus in the lumi package to distinguish methylated versus unmethylated sites on the IlluminaHumanMethylation27k chip. I find these functions in "Analyze Illumina Infinium methylation microarray data", but nowhere else. Session info et al., below. Any help? Thanks, Rich McEachin ------------------------------- > ??gammaFitEM No help files found with alias or concept or title matching ?gammaFitEM? using fuzzy matching. > sessionInfo() R version 2.12.2 (2011-02-25) Platform: x86_64-pc-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] lumi_2.2.1 Biobase_2.10.0 loaded via a namespace (and not attached): [1] affy_1.28.1 affyio_1.18.0 annotate_1.28.1 [4] AnnotationDbi_1.12.1 DBI_0.2-5 grid_2.12.2 [7] hdrcde_2.15 KernSmooth_2.23-4 lattice_0.19-17 [10] MASS_7.3-11 Matrix_0.999375-46 methylumi_1.6.1 [13] mgcv_1.7-3 nlme_3.1-98 preprocessCore_1.12.0 [16] RSQLite_0.9-4 tools_2.12.2 xtable_1.5-6
