rather stick with pdf or ps as I am using latex.
thanks,

The data for a file is typically the following:
> d
V1 V2
1 1 293
2 2 101
3 3 63
4 4 53
5 5 42
6 6 19

My code:
d <- read.table(url("http://ece.ubc.ca/~nazareno/85247.arrivalRates"))
plot(d)
f.exp.nw <- nls(V2 ~ a. * exp(-b. * V1), data = d, list( a. = d$V2[1], b. =
0.05))
f.exp5.nw <- nls(V2 ~ a. / (1+ b. *V1), data = d, list( a. = d$V2[1], b. =
2))
lines(d$V1, predict(f.exp.nw), col = "royalblue")
