In my research, I primarily use R, but I try to use existing code if available. In neuroimaging and other areas, that means calling MATLAB code. There are some existing solutions for the problem of R to MATLAB: namely the R.matlab package and the RMatlab package (which can call R from MATLAB as well). I
