Hello,
I would like to know how to display values for points in a plot funtion. For
example,
plot( y=dat$a,
x=dat$b,
main="plot1",
ylab="a",
xlab="b",
ylim=c(-10, 10),
xlim=c(-10, 10),
type = "p",
pch=17,
col=<vector of colors depending on the value of "b">,
cex=1.5
)
How can I add a label to each of points here, if I have a list of values
associated with the point.
Thanks in advance.

It depends on what you mean by display values. In addition to the other suggestions also look at the identify function as well as TkIdentify and HTKidentify in the TeachingDemos package. -- Gregory (Greg) L.
