R help - May 2009 - maxLik package

Hi all. 
Recently i have been used maxlik package for optimizing a function with 5
parameters but i couldn't define gradient argument in function maxLik;

How i can define a command to receive my goal? Whether I can change the core of
this package?
 
Thanks for your attention and reply

I don't understand.  The help page for "maxLik" says that if the 
"grad" argument is 'NULL', "numeric gradient will be
used."


      If this does not answer your question, please read the posting 
guide "www.R-project.org/posting-guide.html" and provide commented, 
minimal, self-contained, reproducible code illustrating something you 
tried that didn't quite work.  I believe this will increase your chances 
of getting more useful suggestions quicker. 


      Hope this helps.
