[R] R studio installation

[David L Carlson]

R Studio loads R if it can find it. Since you have installed R, the error message means that R Studio can't find it or is not sure which version to use. The part of the message that says "please select the version of R to use" should give you a dialog box to use to navigate to the directory that contains R. Once you have done this, R Studio will remember where it is. The most likely explanation is one of these:

1. You installed R in the default location "C:\Program Files\R" but you have multiple installations as a result of updating R. By default R creates a new subdirectory for each new version. As a result R Studio does not know which one you want.

2. You installed both 32-bit and 64-bit versions of R so R Studio does not know which one to use.

3. You installed R in a location other than the default location and R Studio cannot fine it.

But if the answer to the question "Does R load on its own?" is "no" then this probably is the right place to ask for help. Of course, I would probably just suggest re-installing R, but someone else here might have better answers.
