My question is: Do you know what toolkit between Qt, Gtk+ or Tcl/tk is better to develop an app with RInside?
I think I can do it with any of them, but I just find examples of RInside using Qt.
Can I use, for example, Gtk or Tcl/tk also?, and... What do you think is the best choice to make an efficient GUI for a program in R?
Thanks
I can only speak for the Qt bindings which I have worked on, and which are documented via the following:
an entire examples subdirectory of the sources / installed package devoted to this]
blog posts about this several times which comes up as the first Google hit for 'RInside Qt'; similarly for several of my presentations which featured this
the entire chapter 9 in my Rcpp book
You can probably work something out for Tcl/Tk and Gtk -- but given that RInside and Rcpp are C++ based, Qt seemed like a natural fit.
