Dear all, I haven't been working with R before, but has been asked by my colleagues to investigate the possibility of using R plotting capabilities from external (C) code. They have several plotting functions, implemented in R, that are needed to be included in a front-end Windows-based application. As far as I understood, R.dll is a dll that serves external R calls.
1) My first question is if I need a complete R installation on a user machine to be able to perform such calls? If R.dll only passes the calls to R interpreter then the answer is, probably, "yes".. 2) If the answer on the first question is "yes". For us it is not an option to have R installed on a user's side. How difficult, if possible at all, would it be then to extract and compile all C code related to R graphics into a stand-alone library to link our user application to? So that in my own C code I call C-equivalents of R internal graphical functions, such as "do_rect" or "do_plot_xy". I assume that would include at least compiling the C code of standard packages "grDevices" and "graphics", but perhaps, it is much more than just that? I am afraid these packages would depend on the other core packages of R. Plus some other obstacles I cannot foresee. I cannot myself estimate such an undertaking because of the lack of acquittance with R. I would really appreciate your opinion and reasoning. If this way is not relatively easy or doable, I will convince my colleagues to write an alternative plotting functions using other means. Thanks you all very much, Julia ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
