res.plot: Plot resilience indices

Description

The function creates box plots for selected years of the resilience indices as calculated by res.comp, and is intended for quick visualization.

Usage

res.plot(list.name, select.yr = NULL,
         param = c("resist", "recov", "resil", "rel.resil",
                   "rec.period", "avg.rec.rate",
                   "tot.abs.grow.red", "tot.rel.grow.red",
                   "avg.abs.grow.red", "avg.rel.grow.red"))

Value

Box plot.

Arguments

list.name

a list as produced by res.comp.

select.yr

an integer or vector specifying the year(s) to be plotted (e.g., c(1948, 1992)).

param

a character string specifying the resilience index to be plotted. Argument matching is performed.

Details

The function creates a box plot for a selected resilience index showing the full range of variation for individual trees in specific years. Box plots are only created for years for which indices are available for >= 5 series, as this value represents the number of statistics that a box plot represents in its' simplest form.

Examples

## Plot the recovery period for three selected years
data(s033)
res <- res.comp(s033)
res.plot(res, select.yr = c(1976, 1992, 2003), param = "resist")
