R (& S-Plus)
R, or GNU-S, is a free (note there is no qualification, it is completely free) statistical package that provides an impressive array of methods for data analysis, interpretation, and graphical display. Based on the S language first developed by Bell Labs decades ago, it is quite simply the most advanced of what we have access to of the general purpose packages for academic research, and for anyone wanting to keep up with the times it is the package of choice, bar none.

R however does take a bit to become comfortable with compared to some packages as it is primarily command line driven, and as such we are willing to go the extra mile for those who would like to learn it and use it for their research purposes. However, it should be stressed that one can use it in a very applied fashion, only taking from it what is necessary for the data situation at hand and there are many packages that offer dropdown menu capability. In other words, you do not have to become a computer programmer to take advantage of its functionality. In the end though, if you want to use methods that have been developed in the last 30 years and take advantage of today's computing power, this is the package for you, and the big packages like SAS and SPSS lag far behind its capabilities for the academic researcher.
S-Plus can be seen as a proprietary version of the S language, with its most noticeable difference being that it comes with a sophisticated gui out of the box. S-Plus and R are very compatible with one another in most respects, however R has near daily updates and many, many more packages and offerings.
- Other notes:
- You do not have to come to us to obtain R. It is free to all.
- SPSS, starting with version 16, now has the ability to run R scripts as long as R version 2.5 (or newer) is installed on the machine. However, if you know how to use R, there is little to no reason to use SPSS.
