I have inherited a R package from a previous colleague. I am trying to clean up the stated package dependencies in the DESCRIPTION file as I have noticed several of them are superfluous.
Since there are over 30 stated dependencies, however, I would rather not have to check each one manually to see if it is actually needed. I also have a sneaking suspicion that there may be a few dependencies missing from the DESCRIPTION as well.
Ideally I would like to be able to analyze the package's source code to automatically determine what dependencies are needed. I tried to find a tool or package that could do this but haven't had any luck so far.
