I have a data package �pmartRdata� hosted in a drat repository here:
https://github.com/pmartR/drat following the instructions here:
https://cran.r-project.org/web/packages/drat/vignettes/DratStepByStep.html
The package installs fine via install.packages(�pmartRdata�, repos =
�https://pmartR.github.io/drat�). I have included it under Suggests and added
�https://pmartR.github.io/drat� to the Additional_repositories field in the
DESCRIPTION of a package I am submitting to CRAN. I�m getting failures on
Debian/R-devel and Windows/R-devel when running examples that use this package:
`Error in library(pmartRdata) : there is no package called �pmartRdata�`
Checks on rhub via `rhub::check_for_cran` for ubuntu,fedora, and windows do not
have this problem. What do I need to do to get it to install on CRAN
submission machines?
Generally, you cannot assume that suggested package is available on CRAN
(or any other) machine. Instead, you have to put the code involving
suggested package inside an 'if()' clause, like:
if (requireNamespace("pkg", quietly=TRUE) {
pkg::do_something()
}
Best,
Serguei.
