This function is useful if you want to work on a package but you need to install it's Suggests packages to build the vignette.

You first need the desc package to run the function. You can install it with install.packages("desc").

The idiom is:

get_deps() # to see what is missing
BiocManager::install(get_deps()) # to install missing deps
