1) Remove your current version of R and reinstall with the
following command:
$ sudo apt-get install r-base
2) Install R again (with the above command) and then configure
the RSTUDIO_WHICH_R environment variable to point to
the newly installed version of R. Details of how to do this are
described at the bottom of the following document:
http://www.rstudio.org/docs/advanced/versions_of_r
On Linux, RStudio uses the version of R pointed to by the output of the following command:
which R
The which command performs a search for the R executable
using the system PATH. RStudio will therefore by default bind to the
same version that is run when R is executed from a terminal.
For versions of R installed by system package managers (e.g. r-base on Debian or Ubuntu) this will be /usr/bin/R. For versions of R installed from source this will typically (but not always) be /usr/local/bin/R.
If RStudio is unable to locate R using which R, it will fall back to scanning explicitly for the R script in the /usr/local/bin and /usr/bin directories.
If you want to override which version of R is used then you can set the
RSTUDIO_WHICH_R environment variable to the R executable that you want to run
against. For example:
export RSTUDIO_WHICH_R=/usr/local/bin/R
Not that in order for RStudio to see this environment variable when
launched from the Ubuntu desktop Applications menu (as opposed to from a
terminal) it must be defined in the ~/.profile file.
