Finding the mode in R, when there is more than one mode

Question

I would like R to output all of the modes for a particular group. Currently, R is giving me just the single mode, which is fine if there is only one mode. However, I would like an output of all modes, if more than one exists. Below is the function I am using for the mode, and I was wondering how it could be modified so that I could do this?

Mode <- function(x) {
uni <- unique(x)
uni[which.max(tabulate(match(x, uni)))]
}

Here's one way in base R -

Mode <- function(x) {
 a <- table(x)
 as.numeric(names(a)[a == max(a)])
}

x <- c(1,2,2,3,3,4)

Mode(x)
[1] 2 3

You can use 'modeest' package on CRAN. mvf() function stands for (most frequent value(s)) in the package returns mode(s) of given array.

mfv(x) # returns the most frequent value(s) for vector x.

For more information refer to documentation here.
