can I add ordinary graphics commands to a contourplot? my naive attempts are telling me that plot.new() has not yet been called when I try to add text(1,1,"hi") or points( c(0,1), c(1,0) )?
[or do I need to rewrite another contourplot with the old graphics system. the basics are probably looking at adjacent points, pretending that they are linear, and mark where a line between them intercepts the level, and then hope that some sanity prevents me from connecting disconnected levels. not my plan...] ---- Ivo Welch (ivo.we...@gmail.com) http://www.ivo-welch.info/ ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
