Instead of starting to code in Matlab, I recently started learning R, mainly because it is open-source. I am currently working in data mining and machine learning field. I found many machine learning algorithms implemented in R, and I am still exploring different packages implemented in R.

I have a quick question: how do you compare R to Matlab for data mining application, its popularity, pros and cons, industry and academic acceptance, etc.? Which one would you choose and why?

I went through various comparisons for Matlab vs R against various metrics but I am specifically interested to get an answer for its applicability in Data Mining and ML. Since both languages is pretty new for me I was just wondering if R would be a good choice or not.

I appreciate any kind of suggestions.
