My thoughts on data mining, machine learning, programming languages, open-source software and general nerdery. As most readers are probably aware, the free Learning r studio for r statistical computing pdf for R, called RStudio, was recently released for general use and it immediately made huge waves within the R community. IDE stands for Integrated Development Environment. IDEs typically provides a rich set tools developing in some target language.

MATLAB, and even vanilla R’s GUI. RStudio plays to this analogy very well, and makes modifications where appropriate. RStudio provides many features that are lacking in the standard R GUI, and improves on features that do not work properly in the Windows R GUI. The interface always looks the same, and all I need is a web browser to access it. I only had a few very minor glitches to deal with. Armed with sudo access to a machine on a research cluster at work, I was able to simply download the RPM and install it using the instructions provided on the web site.

I was asked for my login credentials. I just did a yum upgrade R, and RStudio logged me in with no problems. What showed up on my browser screen was beautiful! I will have to go panel by panel, but even then I will have missed cool features.

And dangerous if not debugging. RStudio provides many features that are lacking in the standard R GUI, how would I incorporate these things in order to make these two graphs? I actually don’t know anyone that uses it, it’s really helped clean up my desktop, the user can comment and uncomment a bunch of lines at once. Line version of R, completion of parentheses or quotation marks. All plots are saved in this panel, or even copy it to the local machine’s clipboard!

The R command prompt still looks the same. Damn, what am I supposed to do? But when the GUI finished loading, the familiar R command prompt appeared in all is 1970ish glory. I immediately started typing commands and seeing fields in the other panes populate and change to display different usages. Saves R sessions correctly, and when I return to RStudio, ALL of my work is there! I gave up several years ago.

RStudio and then return, everything is there! The Stop Execution button in the console actually works. I made an error, or because the computation is killing my system’s performance. In R GUI, particularly on MacOS X, the Stop Execution button did absolutely nothing, because there was typically a spinning beachball preventing me from clicking it.

Saves R sessions correctly — that is a huge feature! I am sure there is; i used the same and I got the Rstudio up and working. It’s also the fact that I do not need a bunch of terminal windows, i test it with two users in the same time. I immediately started typing commands and seeing fields in the other panes populate and change to display different usages. These missing features are a tad disappointing; may I know if there’s a way to connect to Amazon S3 from this?
