I wasn't aware of FastRWeb. My understanding is that OpenCPU could handle ggplot2 graphics--is this the case for FastRWeb? What about providing a RESTful service interface?
In a sense the original question was asking for a GIS replacement in R. CartoDB below as a commercial service provides map layers that Leaflet could access through URI calls, but accessing the internal PostGIS that CartoDB maintains is another matter. Maybe a more sensible architecture (for me) is OpenCPU+GRASS+Leaflet+JQuery. I haven't said what I was up to: display of biogeophysical indicators in the Niger RIver Basin. However, this has nothing to do with R--I wrote my own REST server in Flask to provide some functions such as histograms, approximations of subbasins, etc. It became clear that I was duplicating the functions of an honest GIS; I needed GDAL functions, projections... (Fools rush in where angels fear to tread, and there was no one around to disabuse me of my ignorance.)
