Geometric Mean This functions creates a geometric mean of a numeric vector.

Description

Geometric Mean This functions creates a geometric mean of a numeric vector.

Usage

geom_mean(x, roll_window = length(x))

Arguments

x	numeric vector or dataframe column.
roll_window	numeric - length of the vector, or can be used to build a rolling geometric mean.

Value

Returns the geometric mean of a vector, or one number.

Examples

library(tibbletime)
library(purrr)
geom_mean_3 <- purrr::partial(geom_mean, roll_window = 3)
geom_mean_roll_3 <- tibbletime::rollify(geom_mean_3,window = 3)
data <- c(20,25,38,15,70)
geom_mean(data)
geom_mean_roll_3(data)
