OK, for the record, this is not my homework, thanks for asking!
Also, I am sure I could have phrased my question more eloquently, but (hence
the newbie qualifier) I didn't. The code I posted was for the plot I want,
only smoothed i.e not based on random sampling from the distribution.

How do I do that with dchisq?

By explicitl
x <- seq(from = 0, to = 10, by = .01)
plot(x, dchisq(x = x, df = 1), main = "title", sub = "subtitle", type = "l",
xlab = "x-title", ylab = "y-title", ylim = c(0, .4), col = "red")
lines(x, dchisq(x = x, df = 2), type = "l", col = "green")
lines(x, dchisq(x = x, df = 3), type = "l", col = "blue")

Thanks, but that wasn't what I was going for. Like I said, I know how to do a
simple chi-square density plot with dchisq().
What I'm trying to do is chi-square / degrees of freedom. Hence
rchisq(10,i)/i).
How do I do that with dchisq?

Hi! This is going to be a real newbie question, but I can't figure it out.
I'm trying to plot densities of various functions of chi-square. A simple
chi-square plot I can do with dchisq(). But e.g. chi.sq/degrees of freedom I
only know how to do using density(rchisq()/df). For example:
plot(1,
