Missing option to install packages from source URL

[javi-gv94]

Missing option to install packages from source URL. I got an issue while installing 'biom' package. It has been removed from the CRAN repository, so the r_package resource fails to install it.
Example suggestion:
r_package "biom" do
action :install
tarball_base_uri :'https://cran.r-project.org/src/contrib/Archive/biom/biom_0.3.12.tar.gz'
end
Thank you.
