Search for "MLE" on Rseek.org and among other results check the Task
Views. Also, search for "MLE" in "vignettes" on RSiteSearch [1].

To get a good list of MLE-related functions in R, try something
similar to the following (you can also do this graphically with
RcmdrPlugin.sos):
> require(sos)

>  .sos <- findFn('mle')
found 642 matches;  retrieving 20 pages, 400 matches.

>  grepFn('mix', .sos, column='Description', ignore.case=TRUE)

>  summary(.sos)

Call:
findFn(string = "mle")
