[R] maximum likelihood estimate

[Spencer Graves]

	  I suggest you go to "www.r-project.org" -> CRAN -> (select a local 
mirror) -> Packages.  Among the offerings there, you will find the 
following:

distr	Object orientated implementation of distributions
distrEx	Extensions of package distr
distrSim	Simulation classes based on package distr
distrTEst	Estimation and Testing classes based on package distr

	  I don't know that any of these will solve your problem, but if you 
try them and still have problems, I suggest you then PLEASE do read the 
posting guide! "www.R-project.org/posting-guide.html", and submit 
another question based on what you've learned in the interim.

	  Hope this helps.
