[R] maxLik package

[spencerg]

      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.
