Hello all,
I'm trying to graph a scatterplot of a large (5,000 x,y coordinates) of data with the caveat that many of the data points overlap with each other (share the same x AND y coordinates). In using the usual "plot" command, > plot(education, xlab="etc", ylab="etc") it seems that the overlap of points is not shown in the graph. Namely, there are 5,000 points that should be plotted, as I mentioned above, but because so many of the points overlap with each other exactly, only about 50-60 points are actually plotted on the graph. Thus, there's no indication that Point A shares its coordinates with 200 other pieces of data and thus is very common while Point B doesn't share its coordinates with any other pieces of data and thus isn't common at all. Is there anyway to indicate the frequency of such points on such a graph? Should I be using a different command than "plot"? Thanks, Wayne ______________________________________________ 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.
