SAS-vs-RR Vs SAS
R and SAS are leading Data Analytics tools. R is open source and object oriented design. It has huge advantages of thousands of packages for extensibility. However it has demerit of scalability. It runs on machine memory. If needs to run huge data the proposed memory needs to be used in the machine otherwise it won’t handle that huge data sets.

SAS is the leader in Analytics tools. It is paid tool. The decision trees are done by SAS miner which is very expensive. However R does not offer many tree algorithms. SAS does not have memory issues like R and it is more flexible it can handle any amount of huge data. SAS has extensive documentation is another big advantage. R is open source and it has quite same extensive documentation like SAS. In market SAS has keep it strong position and the new data analytics projects are prefer to use R. Most of the current projects which are run by SAS are migrating to R to save the cost. Mix of the projects is run by both. In nutshell for job market R and SAS skills are highly demand in the current market.
