Both Rattle and R Commander are very good GUI’s (graphical user interface) for R, and considerably easier for a beginner than the command line console ( but I am more partial to RCmdr for normal statistical analysis while Rattle seemed to have better Data Mining Interfaces and functionality).
Here is a snapshot for both of them.
Installing them both is a breeze as you set a CRAN Mirror from Normal R Console and install package from list of package names . R has hundreds of packages (All free!!) and you can thus install specific packages to your need and usage.The software R automatically downloads and installs them.
Installling both these GUI will ensure you cut down the time to learn commands as you can first click and try and learn the syntax that is auto generated side by side.
