R can be very useful for prototyping and some exploratory work. However, I'd like to know what kind of on-line
or real-time
applications have you (the SO reader) successfully deployed using R and why did you choose R for that task.
Questions:
- What kind of problem did it solve? (trending, analysis, etc.)
- Why did you choose R over other programming languages? (pros/cons: speed, scaling, etc.)
I'm looking for first-hand experiences, so please do not answer unless you have that.
