install_if_missing

Manage dependencies during package
development. This can retrieve all dependencies that are used in ".R"
files in the "R/" directory, in ".Rmd" files in "vignettes/" directory and
in 'roxygen2' documentation of functions. There is a function to
update the "DESCRIPTION" file of your package with 'CRAN' packages or any other remote package.
All functions to retrieve dependencies of ".R" scripts and ".Rmd" or ".qmd" files can
be used independently of a package development.
