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. ------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Jeff Newmiller Sent: Tuesday, April 14, 2015 7:43 AM To: John Kane; Sojood Malkawi; r-help@r-project.org Subject: Re: [R] R studio installation 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. --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
