R help - Mar 2009 - Plotting pdf of function

Hi Guys,
I'm a numbie to R.
I searched the forum for plotting pdf's of functions but couldn't find
one
that explained my question.

I have been asked to plot the pdf  fX(x) = 1/pi(1+x^2). -infinity < x <
infinity.

I would be greatfull if someone might point me to a webpage that might give
me a hand.

Kindest regards
Beetle

have a look at ?curve(), e.g.,

curve((1 + x^2) / pi, -15, 15)


I hope it helps.

Best,
Dimitris
