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.
