I am developing an R package that depends on installing another R package on the users system.
I added the dependency file: pkgname in the DESCRIPTION file and imported (pkgname) into NAMESPACE. What I was hoping to do was check if pkgname was installed and if not install.packages (pkgname, repos = "CRAN or Rforge or wherever the package is"), if not.
However, when I try to install my package, I get an error message:
ERROR: dependency 'pkgname' is not available for package 'mypkg'
Does anyone know how to implement the installation of pkgname, should pkgname no longer be on the system?
Many thanks
