(iv) Use ggplot2 - particularly geom_segment (http://had.co.nz/ggplot2/geom_segment.html) and stat_spoke (http://had.co.nz/ggplot2/stat_spoke.html) Hadley -- http://had.co.nz/ ______________________________________________ R-help@r-project.org mailing list 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.
