Hi, I am currently building an R package and I am facing a peculiar problem where some of the functions does not work within the package. However, if I source the script the function works. For example, in a method for parallelization of analysis on each chromosome simultaneously I am receiving error at the following position of the code:
# this profile the information chromosome wise and results in "clRes" > clRes = clusterApplyLB(cl, Chrs, profilingChr, GenoRanges = GenoRanges, Sample = Sample) > class(clRes) [1] "list" > clRes [[1]] S4 Object of class GElist; 14 features start : 14350 69251 84185 116264 153924 end : 18349 73250 88184 120263 157923 chr : chr20 chr20 chr20 chr20 chr20 strand : * * * * * binscore : NA > chrcomb <- sapply(result, function(x) rbind(x)) Error in rbind(x) : no method for coercing this S4 class to a vector The above code is part of a function. If I run this code interactively or by sourcing the script it runs fine. However, when I execute the function from the installed package it gives me the above error. I could not find any solution to this. Any insight into the above problem would be highly appreciated. > sessionInfo() R version 3.0.0 (2013-04-03) Platform: x86_64-unknown-linux-gnu (64-bit) locale: [1] C attached base packages: [1] parallel stats graphics grDevices utils datasets methods [8] base other attached packages: [1] BSgenome.Hsapiens.UCSC.hg18_1.3.19 BSgenome_1.28.0 [3] methylPipe_0.99.0 Rsamtools_1.12.3 [5] Biostrings_2.28.0 GenomicRanges_1.12.4 [7] IRanges_1.18.1 GOstats_2.26.0 [9] RSQLite_0.11.4 DBI_0.2-7 [11] graph_1.38.2 Category_2.26.0 [13] AnnotationDbi_1.22.6 Biobase_2.20.0 [15] BiocGenerics_0.6.0 snow_0.3-12 loaded via a namespace (and not attached): [1] AnnotationForge_1.2.1 GO.db_2.9.0 GSEABase_1.22.0 [4] RBGL_1.36.2 RCurl_1.95-4.1 XML_3.96-1.1 [7] annotate_1.38.0 bitops_1.0-5 gdata_2.12.0.2 [10] genefilter_1.42.0 gplots_2.11.0.1 gtools_2.7.1 [13] limma_3.16.5 marray_1.38.0 rtracklayer_1.20.2 [16] splines_3.0.0 stats4_3.0.0 survival_2.37-4 [19] tools_3.0.0 xtable_1.7-1 zlibbioc_1.6.0 Thanks, Kamal [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
