Hi all, I'm writing a program in C++ in witch there should be some graphical outputs. To do so, I would like to use R with the command : R --no-save < cmdfile.R , where I put the R graphic commands in the cmdfile.R file. I call R from my C++ code but as R seems to run in batch mode, there are no graphical outputs! How can I do to get the graphics outputs ? -- Sincerely

Hi all, I would like to test the relevance of a vector field (i.e. if the vectors are organized or not).
