modal value

Description

Compute the mode for a vector of numbers, or across raster layers. The mode, or modal value, is the most frequent value in a set of values.

Usage

## S4 method for signature 'ANY'
modal(x, ..., ties='random', na.rm=FALSE, freq=FALSE)

## S4 method for signature 'Raster'
modal(x, ..., ties='random', na.rm=FALSE, freq=FALSE)

Arguments

x

vector of numbers (typically integers for modal), or a Raster* object

...

additional (vectors of) numbers, or additional Raster* objects

ties

character. Indicates how to treat ties. Either 'random', 'lowest', 'highest', or 'NA'

na.rm

remove (ignore) NA values

freq

return the frequency of the modal value, instead of the modal value

Value

vector or RasterLayer

Examples

data <- c(0,1,2,3,3,3,3,4,4,4,5,5,6,7,7,8,9,NA)
modal(data, na.rm=TRUE)
