Correct - that why I am limited to using the specified output formats. > The only way to make it more "R-like" would be to re-implement the rendering > in R (or Rcpp or using the grid package). Yes - I want to render the generated graphs in a graphics device in R, as if I would use a plot(1,1) command. > > To get a vector based image, your code suggests you can use the SVG format. > But again, that does not have anything to do with R. As vector I have sag, eps, and tikz formats - and the R part is: can I render these in an R device. I am not interested in R-like coded in the package, I am simply looking for a way to display this in an R device.
