Genuine question - what is the use of all these versus something like R or Pandas that is actually usable in production as well.<p>What is missing in R/Pandas that makes people choose other pieces of software that does something very similar? Commercial versions of software probably has an edge in support/performance/libraries...Or (as with Simulink ) provides a very specific piece of functionality or integration.<p>But what is the general use case? Even Mathworks has acknowledged the need to integrate with the huge R community out there - <a href="http://blog.wolfram.com/2013/05/22/why-would-a-mathematica-user-care-about-r/" rel="nofollow">http://blog.wolfram.com/2013/05/22/why-would-a-mathematica-u...</a>
