The qDIST() functions are the inverse of the pDIST() functions, that is to
say, the inverse CDFs of whatever distribution  you are interested in.

Your code is asking it to plot values of the inverse CDF from x from 4000 to
9000, which are impossible values. (I hope the reason for this is evident to
you)

I'm not quite sure what you are meaning to plot, but you may perhaps mean
the pDIST() functions instead. Certainly changing to plnorm() works on my
machine, as does dropping xlim=c(4000,9000) and letting curve plot over the
well-defined range [0,1].

your error messages.
