[R] Display time of PDF plots

[Bert Gunter]

1. Plot a random sample of the points (e.g. of rows of matrix/dataframe
containing "x" and "y" columns

2. See the hexbin package

3. Check out the graphics taskview on cran:
https://cran.r-project.org/web/views/Graphics.html
(though it may be somewhat dated by now)

4. Internet search:  e.g. on "display scatterplots with thousands of
points"
typical hit:
https://stackoverflow.com/questions/7714677/scatterplot-with-too-many-points

5. Search/Post on stats.stackexchange.com instead.
