My Youtube video using free R-Studio for newbies and installing free R packages from CRAN or R-Forge

My Youtube video using free R-Studio for newbies and installing free R packages from CRAN or R-Forge

I have just posted a new video on the amazing combination of all these tools.

Why R-Studio?

There is no difference if you use are using Eclipse or Netbeans as an integrated development environment, I love this free tool R-Studio which should be added to your arsenal for any model prototyping or development. It can be used on any major operating system platform including Mac OSX, Linux, or Windows. It also has a server edition you can load up on a remote server for developing through a browser session including an Apple Ipad. Pretty neat compared to something like Matlab Mobile. This is the primary reason why I switched from Matlab to R.

The confusing difference between CRAN and R-Forge

As a newbie, I could not find the difference with these R package repositories. As a discovery on Stackexchange.com, it was simply explained CRAN contains your milestones releases of R packages. This basically means they are more stable and could be major releases as well. As some R packages have many developers to the package, you could get changes every few hours which may make the package unstable if there was a potentially bad change. As a result, the package administrator may release the milestone into CRAN

R-Studio and CRAN

As you will find in this video, I would feel more comfortable to stick with CRAN and so does R-Studio. This video shows you how ridiculously easy it is to install an R package from CRAN. As I will start depending on these R packages for my production environment,   I would have no choice but do this. I am a sure a large bank or hedge fund would feel these same way. You can still manually install R packages from R-Forge as well.

A Thanks Goes To….

Thanks to this R community for developing these pretty amazing tools and packages. Best part is the documentation is definitely adequate to get me started fairly quickly with confidence as well. I am sure they spend a pretty huge amount of selfless time to get these tools to the point where they are.
