Compound annual growth rate

Source: R/trends.R
CAGR.Rd

Given a variable y indexed by a time vector x, calculates the compound annual growth rate. Note that CAGR assumes that the x refer to years. Also it is only calculated using the first and latest observed values.

Usage

CAGR(y, x)

Arguments

y

A numeric vector

x

A numeric vector of the same length as y, indexing y in time. No NA values are allowed in x. This vector is assumed to be years, otherwise the result must be interpreted differently.

Value

A scalar value (CAGR)

Examples

# random points over 10 years
x <- 2011:2020
y <- runif(10)

CAGR(y, x)
#> [1] 0.2852101
