Details

One of the suggestions to avoid heavy dependencies is to put parent packages that are not frequently used to 'Suggests' and to load them when the corresponding functions are used. Here the check_pkg function helps to check whether these parent packages are avaiable and if not, it prints messages to guide users to install the corresponding packages.
