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"?
