R help - Oct 2007 - plot the chi-square distribution for n=1 through 10, on one plot

Dear help list.

I would like to plot the chi-square distribution for n=1 through 10, on
one plot.

How do I go about doing that?

I know how to plot one chi-square (using curve() for example), but
plotting 10 on one plot, that is too difficult for me.

I greatly appreciate your help.

Here is one way:

curve(dchisq(x,1), from=0, to=15)
for(i in 2:9) curve(dchisq(x,i), add=T, from=0, to=15)

have you tried add = TRUE?
