R help - Dec 2006 - Plotting individual survival plots

Using the survival library, it is possible to get a plot of all the subjects
in a sample and it is possible to get a plot of all subgroups in the same
plot. How does one get a separate plot for each subgroup?

plot(survfit(Surv(time,death==1)~group),col=1:10)

The above results in a hideous graphic representation.

I would prefer to specify

par(mfrow = c(2, 5))

and have each plot separately

There is an example in ?survfit of how to plot a single subgroup, and you 
can just wrap it in a loop to plot all the subgroups.
