How to find mode(s) of a vector in R?
Just like mean and median there is no in-built function in R to find the mode.
We can make use of the following user created function for this purpose
> Modes <- function(x) { ux <- unique(x) tab <- tabulate(match(x, ux)) ux[tab == max(tab)] }
Example
> x<-c(3,2,3,4,3,2,1,2,3,45,6,7,6,4,3,32,4,5,6,4,4,3,4,5,4,4,3,6) > Modes(x) [1] 4
We have created a function called modes because a data can have more than one mode as shown below −
> y<-c(3,2,3,4,3,2,1,2,3,45,6,7,6,4,3,32,4,5,6,4,4,3,4,5,4,4,3,3) > Modes(y) [1] 3 4
