[R-pkg-devel] Installation error when submitting package to CRAN

[Jeff Newmiller]

You should not use "library(anything)" in a package. You should rely on the Imports: field in the DESCRIPTION file along with importFrom() in your NAMESPACE file, or the Suggests: field in the DESCRIPTION file and if (requireNamespace("anypackage"))  {anypackage::somefun} else {# avoid using anypackage}. See WRE 1.1.3.1.

But in this particular case this might be a temporary glitch on the CRAN server.
