I guess I didn't mention that I'm trying to do this in ggplot2 where I have
my color set up via:
geom_point(aes(colour = Date))
Not sure how to implement your suggestion within the confines of ggplot2.

Maybe this is helpful.
Install ggplot2.
#Create a small example
x <- seq(1:20)
y <- (2*x) + rnorm(length(x),0,1)
id <- rep(1:5,each=4)
dat <- data.frame(x,y,id)
library(ggplot2)
p <- ggplot(dat,aes(x=x,y=y,colour=factor(id)))
p <- p + geom_point()

hi all,
suppose I have a file with several columns, and I want to plot all points
that meet a certain condition (i.e. all points in columns A and B that have
a value greater than such and such in column C of the data) in a new but
random color. That is, I want all these points to be colored diffe
