RStudio Error – “ERROR r error 4”

A few weeks ago, I wrote a post on TERR compatible versions of R and RStudio. At that time, I realized I needed to update my RStudio and R versions. In doing that, I ran into an RStudio error when launching my newly updated RStudio.  Since I ran into this problem, I am sure other users will too.  
RStudio Error
 
This error occurs when RStudio can’t find the installation of R. Fixing it is super simple. Simply hold down the Ctrl key when launching R and a popup will appear that allows you to specify the R installation location.
Fixing Error
Now, I’m unsure what order of operations I followed and/or if the order of operations caused my problem, but I would recommend the following…
  1. Uninstall R
  2. Uninstall RStudio
  3. Install new R
  4. Install new RStudio

Hopefully, your installation goes easier than mine did.
