R help - Jan 2004 - estimating mode

Dear all,

I am considering a problem related to density regression. After we got the 
estimation of probability density function f(x), how can we estimate the 
mode of that population?

Does the sm package support mode estimation? If not, is there any other 
function in R can estimate the mode according to the estimation of pdf f(x)? 
Univariate case is ok. If the function further support higher dimensions, it 
is perfect.

Thanks.

You can find some Splus code on Prof. Minnotte's web page:
http://math.usu.edu/~minnotte/research/pubs.html.  You can try and see if
those can be use directly in R.  If not, porting may not be too hard.

Prof. Marron's `SiZer' might also be of interest, but I only know of the
Matlab code that are provided by Steve.
