geomean2: Geometric mean: product form

In nikolaifish/bamExtras: Functions and Data in Support of Stock Assessments with the Beaufort Assessment Model (BAM)

Geometric mean: product form

Description

Simple geometric mean function. The logarithm form (geomean) works somewhat better but can only handle non-zero positive values.

Usage

geomean2(x, na.rm = TRUE, all.na.result = NA)

Arguments

x	numeric vector
na.rm	as in base R functions "a logical value indicating whether NA values should be stripped before the computation proceeds."
all.na.result	Result to return if all values are NA. For some reason prod(numeric(0)) = 1, so the function will return 1 even if all x are NA.
