MakeMortalityRates: Calculate FIA Mortality Rates

In bmcnellis/RSFIA: FIA Tree Mortality Analysis

Description

This workhorse function calculates an average between-census mortality rate at the plot level for a given FIA trees/plots input.

Usage

MakeMortalityRates(trees, plots, debug = T, prog_inc = 500,
  db_ver = 7.2, min_ht = NULL, min_BA = NULL, min_dia = 10,
  test_CNs = NULL)

Arguments

trees	Tree-level FIA dataframe
plots	Plot-level FIA dataframe
prog_inc	Number of plots to process before reporting progress
db_ver	FIA DB version to use for metadata tags
min_ht	Percentile of plot tree heights to include
min_BA	Percentile of plot tree basal areas to include
skip_min_year	Skip first year in dataset? T/F

Details

min_ht and min_BA should be between 0 and 1, db_ver doesn't work with anything besides 7.2 right now.

Value

Plot-level dataframe

Examples

test <- MakeMortalityRates(trees = trees_DF)
