PercentRank: Dense Ranks and Percent Ranks

Description

DenseRank() computes the rank of a vector x and returns the rank as a number. The ranks are consecutive integers beginning with 1. No ranks are skipped if there are ranks with multiple items. So the largest rank value is the number of unique values of x. Unlike rank gives the ranking within the vector x too, but ties are assigned the same rank, with the next ranking(s) skipped.

PercentRank() takes a vector x and returns the percentile that elements of x correspond to.

Usage

PercentRank(x)

Arguments

x

a numeric, complex, character or logical vector.

Value

A numeric vector of the same length as x with names copied from x (unless na.last = NA, when missing values are removed). The vector is of integer type unless x is a long vector.

Examples

# NOT RUN {
(r1 <- rank(x1 <- c(3, 1, 4, 15, 92)))

x2 <- c(3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5)
names(x2) <- letters[1:11]
(r2 <- rank(x2))        # ties are averaged

PercentRank(x2)
# }
