This is pretty easy to do with the ggplot2 package: library(ggplot2) qplot(longdeg, latdeg, data = data, facets = . ~ vessek, size = catch) or maybe qplot(longdeg, latdeg, data = data, facets = . ~ vessek, size = catch) + scale_area() if you want the area of the points proportional to the catch, rather than their radius 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.
