Hello,
I like to have everything on my system in a package. So, I looked around and found no recipe or rpm for Rstudio. This is really a shame because every tutorial on R kinda tells you to install it. Even the Coursera classes in the Data Science track make you install it and send a screenshot to prove it.
So, I spent some time getting it packaged and working. I am placing the spec file and necessary patch here so that google finds it and saves other people the trouble. I'm not wanting to submit the package to Fedora because its more work than I have time for. If anyone else wants to take it from here and submit and/or maintain it, feel free.
