Hello! I have an intention of making a R-wrapper for VTK library ( www.kitware.com ). The libray itself is quite extensive so write an R/C code for the wrapper by hand seems to be impossible. VTK library has automatically generated wrappers for Python and Tcl so generating code for just another language would not be hard. The question is - what tool I should use for that? There is a SWIG tool, but using it means I have to insert wrappers for R into it. Another possibility is using RGccTranscript from Omegahat (but it looks to me it is suitable only for interfacing C-code - not C++ one). Is there an example of building generators of R code from C++ source? If someone has it, would not you share it, please?
