Dear R Gurus,

I have a problem related to plot.
For example, I have two variables, pre and post.

pre <- c(1,2,3,4,5)
post <- c(2,5,7,2,3)

How can I plot a line graph similar to this one?


Would you please provide me a keyword so that I can search. I don't
know what is the name of this type of graph.
