Dear R helpers, I'm planning to work with several mammal species' gene expression profile. So I have to create some annotations (.db) by "AnnotationForge" package for some species I'm wondering whether I can use created annotations with virtualArray during merging data from different platform. If it can, would you please show me how to do it. Note: I'm extremely weak at R language, please be patient with me :) Best regards, Kaj -- output of sessionInfo(): R version 2.15.3 (2013-03-01) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=Thai_Thailand.874 LC_CTYPE=Thai_Thailand.874 [3] LC_MONETARY=Thai_Thailand.874 LC_NUMERIC=C [5] LC_TIME=Thai_Thailand.874 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] org.Mm.eg.db_2.8.0 mouse.db0_2.8.0 BiocInstaller_1.8.3 [4] AnnotationForge_1.0.3 org.Hs.eg.db_2.8.0 RSQLite_0.11.3 [7] DBI_0.2-6 AnnotationDbi_1.20.7 Biobase_2.18.0 [10] BiocGenerics_0.4.0 loaded via a namespace (and not attached): [1] IRanges_1.16.6 parallel_2.15.3 stats4_2.15.3 tools_2.15.3 -- Sent via the guest posting facility at bioconductor.org.
