[R] Plotting Binned Data

[Gundala Viswanath]

Dear all,

I have a binned data that looks like this:

> dat
  (-1,9]   (9,19]  (19,29]  (29,39]  (39,49]  (49,59]  (59,69]  (69,79]
10063374       79       16        4        3        4        4        3
 (79,89]  (89,99]
       6        2

I tried to plot a histogram overlayed with curve.
With the following snippet:

library(lattice)
pdf("myfile.pdf")

hist(dat)
lines(dat,col="red")
dev.off()
__ END__

However the number of bins it plot is not the same
with "dat" (i.e. 10 bins). It only gives 6 bins.
The actual output can be seen in this URL

How can I fix the code so that it gives a exact plot
to "dat" above, with same number of bins and its
respective frequency?
