Generate a matrix to compute Mohn's rho for a single metric

Creates a matrix to compute Mohn's rho for a single metric from retrospective analysis results. A common measure of the strength of stock out the calculation but returns a matrix with the metrics value for the n restrospective runs, in columns, and n + 2 years, in rows.

Usage

mohnMatrix(stocks, metric = "fbar", ...)

Arguments

stocks: An FLStocks object from a restrospective analysis
metric: Metric to be computed, as a character vector or function
...: Additional arguments passed to the metric function

Value

A metrics of n + 2 x n, where n is the numbers of objects in stocks.

# Create retrospective runs
stks <- FLStocks(lapply(0:5, function(i) window(ple4, end=2017-i)))
