I did some research online. Some people use ggplot2 to plot MCF, but it requires some additional coding. http://user2010.org/slides/Shentu.pdf Your help and suggestions are highly appreciated.

In particular, if anyone wants to help improve this (though again, quite a bit already works seamlessly), you may be interested in the following talk (mine) at useR! 2010 next week: http://user2010.org/abstracts/Crisman.pdf We definitely need experts, and also really crave feedback on how Sage can best be of use to the R community (why R is useful to Sage should be obvious).

Hello, I am trying to import an .eps file created with Adobe Illustrator and plot it in a Quartz window (I am using R 2.11.1 GUI 1.34 Leopard build 32-bit (5589) on MacOSx.5.8). I thought of using the PostScriptTrace() to convert my .eps file to RGML, and then use readPicture to plot the file, but the first step already fails (cf below). I also had a look at the add.image( ) example,

Dear UseRs!, Everything about UseR! 2010 was terrific! I really mean "everything" - the tutorials, invited talks, kaleidoscope sessions, focus sessions, breakfast, snacks, lunch, conference dinner, shuttle services, and the participants. The organization was fabulous. NIST were gracious hosts, and provided top notch facilities. The rousing speech by Antonio Possolo, who is the chief
