My favorite software is Matlab, but partly because R is free, more and more people & companies choose to use R as a major working language. Nothing wrong with that, I am at the moment changing some of my Kalman Filter Matlab codes to R.**Quantitative Finance Collector**, and kindly contributed to R-bloggers].

One bothering issue is each software has its own coding rules, for example, in Matlab we use a(1,1) but in R we use a[1,1]; in Matlab we have ones(3,2) but in R we dont have such a command but matrix(1,3,2), etc. (I am always wondering why they can’t be designed in a similar way). It does bring me trouble sometimes, luckily I came across a web page similar as cheat-sheets, it lists those widely used commands in R and corresponding commands in Matlab, very convenient indeed.

Walking Randomly suggests another excellent PDF manual consisting of 47 pages, fantastic! http://www.math.umaine.edu/~hiebeler/comp/matlabR.pdf
