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)

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

Hello!
I have a continous distribution and would like to get mode (the most
frequent value in distribution). I easily found mean, median
and other
basic thing but not mode function. Can anyone help?
I know there my might be problems with multiple modes, but
still I think
that there should be a mode function in R.
Please send mail to R-help list and me, so I can get response faster.
Thank you!
