R help - Jan 2010 - Mode of a histogram

Hi all

I recently Googled to find out how to get the mode from my continuous 
data in R, and came up with this ancient thread from the archives:
http://tolstoy.newcastle.edu.au/R/help/99b/1319.html

But sorting is very inefficient if you have lots of data, so can I 
propose this method:

h <- hist(x, breaks=512)
mode <- h$mids[h$counts == max(h$counts)]

of course, breaks can be whatever is sensible for your data, which you 
can check by running

plot(h)

Apologies if this is ridiculously obvious,

Michael

Mmm. Good to know that sorting is very inefficient.
