To the list of great Matlab alternative I add today RSTUDIO. Although, I usually don't program in R, I am glad to see it is not freezing, and continuously develop as a scientific interested language. I am guessing that this fancy IDE for R, would make it easier to accept among people who are deeply rooted in the EXCELLENT MATLAB IDE. However, doing most of my scientific tasks, and system administration in python, I think Matlab's syntax is equally weird to that of R ;-).
One weird choice of the developers is to call the binary
rstudio... Maybe they don't know about
which is familiar to most system administrators ... oh, well, I guess
I'll have to open a bug ...
