Border color of plot points - R plot

Question

how to create a plot with customized points in R?

I know in R you can use plot to specify the color of the points

plot(......,col="red") makes the points in a scatter plot, for example, red.

How can I specify the border color of the points such that the border color is different from the fill color.

You can plot twice. Once with a "rim color" and second with the "fill color", but the plotting character should be smaller (`cex`). Hadley does something similar in ggplot2 here: http://had.co.nz/ggplot2/geom_point.html (scroll down towards the end). — Roman Luštrik, Jul 18 '12 at 20:24

You can use the bg parameter to handle how a point is filled. On certain types of plotting characters, this will be visible. For example...

plot(1,1,col=3, bg=2, pch=23)

The color is specified in the above command. You can use `col="red", bg="green"` if you'd prefer. I'm using integers. – Jeff Allen Jul 18 '12 at 18:23

For circles, use plot(1,1,col=3, bg=2, pch=21) – Davit Sargsyan Dec 17 '15 at 22:13
