but this is not a probability density function, since lim(abs(x)->
infty)=infty. But there is just a pair of brackets missing in Beetles post.
btw. homework?

have a look at ?curve(), e.g.,
curve((1 + x^2) / pi, -15, 15)
I hope it helps.

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
