Mode: Mode, Most Frequent Value(s)

Description

Calculate the mode, the most frequent value, of a variable x. This makes mostly sense for qualitative data, at most for x being an integer vector.

Usage

Mode(x, na.rm = FALSE)

Arguments

x

a (non-empty) numeric vector of data values.

na.rm

logical. Should missing values be removed? Defaults to FALSE.

Value

Returns the most frequent value. If there are more than one, all of them will be returned in a vector.

Examples

# NOT RUN {
# normal mode
Mode(c(0:5, 5))

Mode(5)
Mode(NA)
Mode(c(NA, NA))
Mode(c(NA, 0:5))
Mode(c(NA, 0:5), na.rm=TRUE)
Mode(c(NA, 0:5, 5), na.rm=TRUE)

# returns all encountered modes, if several exist
Mode(c(0:5, 4, 5, 6))


data(d.pizza)
Mode(d.pizza$driver)

# use sapply for evaluating data.frames (resp. apply for matrices)
sapply(d.pizza[,c("driver","temperature","date")], Mode, na.rm=TRUE)
# }
