A small script to grab the latest RStudio daily build for OS X and install it.

README.md

I like to run the RStudio dailies since Kevin Ushey is always adding good stuff (and it's super-easy to use a stable version if the daily is wobbly).

Rename rsupd.bash to just rsupd (I wanted it to render nicely in the gist so I had to put an extension on it) then put the rsupd script into /usr/local/bin and (from a command prompt) do chmod 755 /usr/local/bin/rsupd

Now, copy the is.rud.UpdateRStudio.plist to ~/Library/LaunchAgents if you want the update to happen automatically. Change the hour/minute if 0730 AM doesn't work for you for some reason. Then use: launchctl load -w ~/Library/LaunchAgents/is.rud.UpdateRStudio.plist to load it (use unload vs load to, well, unload it).

If you want to run it by hand, just enter rsupd as a command prompt.

As stated in the rsupd.bash script, it requires external utilities, so read the comments and ensure you've done that, otherwise the script won't work!
