[R] queueing problems

[Dan E. Kelley]

I have a similar task, and I've figured out that 'nls' is the thing you
want.  There is also 'nlme' but I can't make (the latest version --
3.1-3.tar) it work with my R version (0.99.0).

EX:
        library(nls)
        ... get data
        model.fit <- nls(y ~ exp(x))
        plot(model.fit)
or something like that.
