Density plots, scatterplot smoothers, hexbin plots, bubble plots, histograms, and boxplots are available in the survey package. These are probability-weighted rather than frequency-weighted but it doesn't matter for graphics. You could use them as is (which requires setting up a survey design object) or rip the internals out of them. -thomas ______________________________________________ R-help@stat.math.ethz.ch 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.
