Calculate the widths of credible intervals

Description

Calculate the widths of credible intervals stored in a DemographicArray. If (l, u), is a credible interval, then the width of the interval equals u - l.

Usage

intervalWidth(interval)

## S4 method for signature 'DemographicArray'
intervalWidth(interval)

Arguments

Details

interval must have a dimension of length 2 with dimtype "quantile" specifying the intervals. interval is typically calculated using function credibleInterval.

Examples

#' set.seed(0)
object <- Values(array(runif(n = 20),
                       dim = c(2, 10),
                       dimnames = list(sex = c("F", "M"),
                                       iteration = 1:10)))
interval <- credibleInterval(object)
interval
intervalWidth(interval)
object <- Values(array(rpois(n = 20, lambda = 10),
                       dim = c(2, 10),
                       dimnames = list(sex = c("F", "M"),
                                       iteration = 1:10)))
interval <- credibleInterval(object, width = 90)
interval
intervalWidth(interval)
