When I check it with R CMD check I get a following warning : no visible global function definition for ‘biocLite’ I have used biocLite to load a user defined library from within a function if that library is not pre-installed if(is.element(annotpkg, installed.packages()[,1]) == "FALSE"){ source("http://www.bioconductor.org/biocLite.R";) biocLite(annotpkg) library(annotpkg,character.only=TRUE) } Should I ignore this error or there is a workaround for the warning. My package is working fine though still I guess the warning has to have significance. Please help in clarifying this warning.Your source() call generates the function biocLite() in such a way that R CMD check cannot know, so a workaround is to precede the source() statement with something like: biocLite <- function(x) 0 [I don't know if there is a 'best' way to do this.] In general Warnings are just that - they point you to a possible fault, but there is not enough information for the code to make a final determination.
Or just set ask people (or try yourself) to use install.packages() with the corresponding BioC repository selected. I still do not get the point why install.packages() and friends are not sufficient.
Best, Uwe
