In R, `mean()`

and `median()`

are standard functions which do what you'd expect. `mode()`

tells you the internal storage mode of the object, not the value that occurs the most in its argument. But is there is a standard library function that implements the statistical mode for a vector (or list)?

One more solution, which works for both numeric & character/factor data:

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

On my dinky little machine, that can generate & find the mode of a 10M-integer vector in about half a second.

If your data set might have multiple modes, the above solution takes the same approach as `which.max`

, and returns the *first-appearing* value of the set of modes. To return *all* modes, use this variant (from @digEmAll in the comments):

Modes <- function(x) { ux <- unique(x) tab <- tabulate(match(x, ux)) ux[tab == max(tab)] }

**Is there a built-in function for finding the mode?,** There is a package called modeest which enables to compute an estimate of the mode of a univariate distribution. Its dependency genefilter is There is a package called modeest which enables to compute an estimate of the mode of a univariate distribution. Its dependency genefilter is part of Bioconductor, so it needs to be installed using Bioconductor methods.

There is package `modeest`

which provide estimators of the mode of univariate unimodal (and sometimes multimodal) data and values of the modes of usual probability distributions.

mySamples <- c(19, 4, 5, 7, 29, 19, 29, 13, 25, 19) library(modeest) mlv(mySamples, method = "mfv") Mode (most likely value): 19 Bickel's modal skewness: -0.1 Call: mlv.default(x = mySamples, method = "mfv")

found this on the r mailing list, hope it's helpful. It is also what I was thinking anyways. You'll want to table() the data, sort and then pick the first name. It's hackish but should work.

names(sort(-table(x)))[1]

I found Ken Williams post above to be great, I added a few lines to account for NA values and made it a function for ease.

Mode <- function(x, na.rm = FALSE) { if(na.rm){ x = x[!is.na(x)] } ux <- unique(x) return(ux[which.max(tabulate(match(x, ux)))]) }

A quick and dirty way of estimating the mode of a vector of numbers you believe come from a continous univariate distribution (e.g. a normal distribution) is defining and using the following function:

estimate_mode <- function(x) { d <- density(x) d$x[which.max(d$y)] }

Then to get the mode estimate:

x <- c(5.8, 5.6, 6.2, 4.1, 4.9, 2.4, 3.9, 1.8, 5.7, 3.2) estimate_mode(x) ## 5.439788

It’s the score that occurs most frequently in a group of scores. Sometimes the mode is the best measure of central tendency to use. Imagine a small company that consists of 30 consultants and two …

**The Mode in R,** Calculate the mode, the most frequent value, of a numeric or character vector x. it is not so much the central tendency property of the mode that is interesting Built-in Functions ¶ The Python interpreter has a number of functions and types built into it that are always available. There is an additional mode character

**Mode function,** In R, there are no standard in-built functions to calculate the Mode. Therefore, we are going to create a user function to find the mode of a data A mode of a continuous probability distribution is often considered to be any value x at which its probability density function has a locally maximum value, so any peak is a mode. Python is very robust when it comes to statistics and working with a set of large range of values.

This is the only function in statistics which also applies to nominal (non-numeric) data Finding the Mode. To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

##### Comments

- You need to clarify whether your data is integer, numeric, factor...? Mode estimation for numerics will be different, and uses intervals. See modeest
- Why does R not have a built-in function for mode? Why does R consider
`mode`

to be the same as the function`class`

? - Also works for logicals! Preserves data type for all types of vectors (unlike some implementations in other answers).
- This does not return all the modes in case of multi-modal dataset (e.g.
`c(1,1,2,2)`

). You should change your last line with :`tab <- tabulate(match(x, ux)); ux[tab == max(tab)]`

- @verybadatthis For that, you would replace
`ux[which.max(tabulate(match(x, ux)))]`

with just`max(tabulate(match(x, ux)))`

. - You note that
`Mode(1:3)`

gives`1`

and`Mode(3:1)`

gives`3`

, so Mode returns the most frequent element or the first one if all of them are unique. - As Enrique said: This fails when there is no mode, and instead give you the impression that the
*first*value is the mode. Would have been far better if it returned`0`

or at`NA`

in those cases. - So to just get the mode value,
`mfv(mySamples)[1]`

. The`1`

being important as it actually returns the most frequent value*s*. - it does not seem to work in this example: library(modeest) a <- rnorm( 50, 30, 2 ) b <- rnorm( 100, 35, 2 ) c <- rnorm( 20, 37, 2 ) temperatureºC <- c( a, b, c ) hist(temperatureºC) #mean abline(v=mean(temperatureºC),col="red",lwd=2) #median abline(v=median(temperatureºC),col="black",lwd=2) #mode abline(v=mlv(temperatureºC, method = "mfv")[1],col="orange",lwd=2)
- @atomicules: with [1] you get only the first mode. For bimodal or general n-modal distribution you would need just
`mfv(mySamples)`

- For R version 3.6.0, it says function 'could not find function "mlv"' and the same error when I tried mfv(mysamples). Is it depreciated?
- That's a clever work around as well. It has a few drawbacks: the sort algorithm can be more space and time consuming than max() based approaches (=> to be avoided for bigger sample lists). Also the ouput is of mode (pardon the pun/ambiguity) "character" not "numeric". And, of course, the need to test for multi-modal distribution would typically require the storing of the sorted table to avoid crunching it anew.
