R studio installation
I installed R and then R studio but it doesn't open every time i try to open it it gives me this message "Rstudio requires an existing installation of R in order to work. please select the version of R to use ". i'm using R i386 3.1.3 and downloaded RStudio 0.98.1103 - Windows XP/Vista/7/8. do you have any idea what the problem is??
