Everitt and Geoff Der, Read it Online! This particular comparison although not known in popular culture is an oft repeated argument in the Analytics industry. What makes R Special? One of the biggest reasons for continued Windows dominance is momentum and an easier user experience. Many experimental packages are also available in R.
In this aspect R is the hands down winner, however a word does need to be put in about SAS, since SAS is a paid software with support, any new innovation, or new statistical technique has to be vetted and accepted. SAS is used in many mission critical assignments where merely experimental techniques cannot be allowed to creep in.
While this is necessary for the environment SAS works in, it also means that it will keep playing catchup with R in terms of latest innovations. On the other hand since anybody can upload a package in R, user beware! Therefore in terms of pure statistical capabilities, I rate R higher. Data Handling Data handling is the bugbear of R.
The single largest drawback of R is the way it allocates and handles memory by trying to load the whole dataset in RAM. This can cause severe problems when working on a combination of large datasets and small computers which it always is, your data is always huge and your computer is always puny!
SAS excels in handling large datasets, infact server editions of SAS can chew through TeraBytes of data without any issues whereas R is very likely to throw Out of memory errors or become unresponsive and die. Not to say that R cannot handle big data, it can, but say I have a Laptop with 2 gigs of RAM and a dataset running into millions of records, for the same exercise which SAS can do in 30 seconds, R might take upto a few minutes or even die.
However computing power is cheap and getting cheaper by the day, given enough RAM and computing power, R can also crunch through large datasets efficiently, especially on 64 bit machines.
Ease of Use One of the biggest reasons Linux has never been the runaway success as compared to Windows is that it was so damn difficult to use, install or troubleshoot.
Now take that problem and multiply by 10, and you get the idea of R.
