Dear All,
I am trying to build a package for a set of functions. I am
able to build the package and its working fine. 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.
