edited is associated with the active project, any state-related changes
(e.g. to R repositories) will be updated in the current session.
Usage
modify(project = NULL)
Arguments
project
The project directory. If NULL, then the active project will
be used. If no project is currently active, then the current working
directory is used instead.
