Here, our goal is to illustrate one way to do package development with RStudio.
Imagine after a short time using RStudio for interactive use, that we
are pretty happy using the command line for short commands, but have learned
to really enjoy writing scripts in the Code editor. Even 2- or 3-line commands are much
easier to debug when done in the editor. The directness of typing at the
command line isn’t lost, as our fingers are now trained to hit Ctrl+Enter to
send the current line or selection to the R interpreter—or even
Ctrl+Shift+Enter to send the entire buffer (Command, not Ctrl, for Mac
users). We never need to leave the keyboard unless we choose to.
Along the way, we have been able to create a large script file that we now want to share with a colleague.
How do we do this? There are many ways. We could just send along the entire script, or with just a bit more extra work, we could share our work through a version control system.
