Hi Rainer, You are currently using a java library to create the plot. Your package is basically a wrapper around the java file. 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).
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. Kindly, Stefan McKinnon Høj-Edwards Stefan McKinnon Høj-Edwards ph.d.
