Hi Rex,
It sounds like something that can be done with
?lines
If you would supply with a simple self contained data that represents what
you are trying to plot, then we might be able to better help you.
If you have the data in R, use "dput" to be able to copy paste it into the
email.
Cheers,

Hi,
Try this,
## create a 2D grid with random point sizes
d = expand.grid(x=1:10,y=1:10)
d$size = runif(nrow(d), 1,5)
## create some random links
links= d[sample(seq(1,nrow(d)),20),]
links$id = sample(2:6, nrow(links),repl=T)
## plot
library(ggplot2)
ggplot(d, mapping=aes(x,y)) +
geom_point(
I would like to draw a set of points that are equally spaced in a 2-D
grid. Then I would like to draw lines that illustrate different
directed paths through subsets of points. Imagine that the points
correspond to booths in a conference center, and I want to show the
various paths people took to vi
