R help - Aug 2008 - (no subject)

I am very new user of R project. Sir I am a research scholar. I am doing work on
fitting distributions. Actually sir I want to know that what package is use to
find parameters of pareto distribution by maximum likelihood method. and i want
to find these parameters from my calculated data. Sir I am waiting for your
positive response.
Thanks

Package actuar provides a density function that you can use with fitdistr 
from MASS.  E.g.

> library(MASS)
> fitdistr(x, dpareto, list(shape=1, scale=1))
      shape       scale
   1.7928750   2.4446281
  (0.1569442) (0.3108455)
