Dear R community,
I am creating my own package which uses functions from other packages.
After reading several books/help pages I now would do the following to
safely use some functions from other packages:
1. list them in Imports: (DESCRIPTION file)
2. put importFrom(packagename, functionname1, functionname2) in NAMESPACE
Apparently this now also works without loading the external package with
require() or library() inside the function that uses the imported functions.
Is this the recommended way to do this (even if there may be several
ways...)? Is it save to remove all the library() and require() calls?
Thanks a lot
Jannis
