Install missing packages — install_missing

Attempt to install missing packages from CRAN.

Usage

install_missing_pkgs(pkgs_availability)

Arguments

pkgs_availability: Named logical vector where names are packages -- generally the output of running check_pkgs_availability().

Value

Installs packages from cran using remotes::install_cran() if available else install.packages()

Details

In most cases, is probably safer to clone and use renv::dependencies() -- README.

Examples

# should verify pkgs are available on CRAN -- example below wouldn't work #
# because madeUpPkg doesn't exist on CRAN
