Hi, I am trying to package an R script (that requires certain R packages) into a galaxy tool. Any advice would be deeply appreciated! I have tested it on planemo and it works. When I tried the version I uploaded onto the toolshed, I got an error saying that the R packages do not exist. I next added the following lines to the R script: source("https://bioconductor.org/biocLite.R") biocLite() biocLite(c("DNAcopy", "preprocessCore")) and I got the following error when running the installed tool on galaxy: Installing package(s) ‘DNAcopy’, ‘preprocessCore’ Warning in install.packages(pkgs = doing, lib = lib, ...) : 'lib = "/usr/local/lib/R/site-library"' is not writable Error in install.packages(pkgs = doing, lib = lib, ...) : unable to install packages Calls: biocLite ... .biocLiteInstall -> .reposInstall -> install.packages Execution halted
