Do you have a measures of "scatter" or can you pick "outliers" that could allow you to produce a "mixed" plot using either density or hexbinned data with only outliers placed after-the-fact using points()?

Subject: [R] scatterplot of 100000 points and pdf file format


Hi,

I want to draw a scatter plot with 1M  and more points and
save it as pdf.
This makes the pdf file large.
So i tried to save the file first as png and than convert it to pdf.
This looks OK if printed but if viewed e.g. with acrobat as document
figure the quality is bad.

Anyone knows a way to reduce the size but keep the quality?
