[R] How to get mode (the most frequent value in distribution) ?

[Liaw, Andy]

A sample from a continuous distribution most likely has no meaningful sample
mode.  Shown below is a way to estimate the location of mode from a kernel
density estimate (using the locfit package):

> x <- rnorm(50)
> library(locfit)
Locfit for R.
August 3, 2000.  (Updated for R 1.7.0, March 21, 2003)

Attaching package 'locfit':


        The following object(s) are masked from package:stats :

         knots 

> x.den <- locfit(~x)
> x[which.max(predict(x.den, newdata=x))]
[1] -0.615337
