[R] mode of a distribution - was (no subject)

[Charles Annis, P.E.]

Perhaps a time out might be helpful.

?which.max will produce the location (index) of the maximum of a numeric
vector, but Paolo doesn't want that.  He wants the location of the most
frequent observation which would be the maximum of the probability density,
which he doesn't have.  

It would be useful to estimate what kind of density represents the data and
then, given this, determine its interesting statistics, including the mode.
