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 ANY
modal(x, ..., ties='random', na.rm=FALSE, freq=FALSE)
# S4 method for Raster
modal(x, ..., ties='random', na.rm=FALSE, freq=FALSE)
Value
vector or RasterLayer. The vector has length 1 and is of the same type as x, except when x is a factor and additional arguments (values) are supplied, in which case the values are coerced to characters and a character value is returned.
Arguments
x
vector of numbers (typically integers), characters, logicals, or factors, or a Raster* object
...
additional argument of the same type as x
ties
character. Indicates how to treat ties. Either 'random', 'lowest', 'highest', 'first', or 'NA'
na.rm
logical. If TRUE, NA values are ignored. If FALSE, NA is returned if x has any NA values
freq
return the frequency of the modal value, instead of the modal value
