I just tried rendering a plot of 166 data point (time series) on my PPC mac, and compared it with the same data rendered by Mathematica. The R plotting is very slow to paint and repaint, compared to Mathematica. This also makes it extremely awkward to use in other documentation such as pdfLatex.
On closer inspection, it looks like the Mathematica plot is just a polyline, while in R it is a B-spline with each marker consisting of 24 B-splines knotted together. Moreover, the spline joints are rounded, which requires computing two circles and intersecting them 26 times at each bend. Is there some reason why the point-markers are not just drawn as circles or squares, instead of doing these complicated and time-consuming knots? -- njg ________________________________________________________________________ PERFORMANCE DYNAMICS COMPANY http://www.perfdynamics.com/ ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
