Finding the minimum R version that a package needs

find_transitive_minR() finds the highest minimum version of R declared by the packages on CRAN that a package depends upon, directly or indirectly. find_required_r() does the same from the installed packages, so it also works for packages that are not on CRAN, and it also says which packages need that version.

Usage

find_transitive_minR(package)

find_required_r(pkg)

Arguments

package, pkg

The name of a package.

Value

find_transitive_minR() returns the minimum version of R as a package_version. find_required_r() returns a list with the version of R that the package itself declares (current), the highest version that it or its dependencies declare (max_required_R), the packages that declare that version (responsible_packages), and the version that each package declares (all_requirements).

Examples

if (FALSE) { # \dontrun{
find_transitive_minR("manynet")
find_required_r("manypkgs")
} # }
