RStudio has a page where they explain how to switch which version of R is used by RStudio: http://www.rstudio.com/ide/docs/advanced/versions_of_r.

So you may be able to install and try the CRAN version (without uninstalling the MacPorts version using sudo port uninstall).

Hi all. I am experiencing very annoying R software problems and am looking for help.

I am using mac OS X 10.8.3. The version for R-studio is 0.97.551. The version for R-console is 3.0.2. I got similar problems in R-studio and R-console.

For R-studio, it often happens that when I type a command in the console window and press enter, the command will disappear and leave nothing in the command history. I even can't retrieve the previous command by the up arrow. I have to retype the command. It happens very often, with probability nearly 50%.

For R-console, almost similar problems. Many commands got stuck. I have to force them to stop.

This scenario happens for even every command, like 'library(Rlab)', 'rbern(100, 0.1)', etc.

I've tried several methods, including uninstall both R-console and R-studio, even have tried to uninstall them through mac terminal. Even I put these two software in the recycle bin, and uninstall them on terminal, R is still there with mac ports when I enter R in the terminal. The problem exists. I don't know whether my mac ports sucks.

I do appreciate your help<330.gif>
