Dear List,While using the --as-cran option for checking one of my packages: R CMD check --as-cran hydroGOF_0.3-3.tar.gz I got the following error message: pkgname<- "hydroGOF" > source(file.path(R.home("share"), "R", "examples-header.R")) > options(warn = 1) > library('hydroGOF') Error in loadNamespace(i[[1L]], c(lib.loc, .libPaths())) : there is no package called ‘class’ However, I don't get any error message when the checking is done without the --as-cran option. Could somebody give me a hint about how to solve this error before submission to CRAN ?
There was a bug in 2.15.0: if your package used a package that used a recommended package (where "used" means listed as Depends, Suggests, Imports...), then you could get this error.
R-patched has this fixed, so you could update to that. If you don't want to update, the workaround is to list "class" explicitly as a dependency of your package.
