I'm working on a web-based app (haven't started coding yet actually, just the UML part). The purpose of the app is to provide certain maps (heat maps for instance), charts, plots, histograms, etc. All those graphs should be generated using a powerful statistical tool (such as R). I've been thinking about D3JS, but I have to deal with points, lines and every single little thing. It's a lot easier in R. Anyway, I just want to know if there's a way to call R (execute R code) from a web-based environment (which I haven't chosen yet).
Thank you.
