EPGMThreshold: Threshold Evaluation

In SwampThingPaul/EPGMr: Implementation of the Everglades Phosphorus Gradient Model

Threshold Evaluation

Description

This function evaluates results of the EPGM model over a simulated period relative to ecological or regulatory thresholds.

Usage

EPGMThreshold(
  time.dat,
  WaterColumn.Thresholds = c(10, 15, 20),
  Soil.Thresholds = c(500, 600, 1000),
  cattail.Thresholds = c(5, 20, 90),
  plot.exceed = TRUE,
  raw.area.output = FALSE,
  results.area.table = TRUE
)

Arguments

time.dat	a data.frame, the raw output from EPGMTime (when raw.time.output=TRUE).
WaterColumn.Thresholds	a list of three water column total phosphorus thresholds to evaluate time output.
Soil.Thresholds	a list of three soil total phosphorus thresholds to evaluate time output.
cattail.Thresholds	a list of three cattail density thresholds to evaluate time output.
plot.exceed	If TRUE base plot will be generate with water column, soil and cattail area exceeded plots.
raw.area.output	If TRUE a data.frame will be printed with all area exceedances calculated for each time step.Default is set to FALSE.
results.area.table	If TRUE a summary results table will be printed in the console. Default is set to TRUE.

Details

As described in the original documentation, the model is designed to simulate marsh enrichment (responses to increasing P load), not recovery (responses to decreasing in load).

Value

This function computes and plots the distance profile along the gradient based on input values

Examples

example<-EPGMTime(case.no=11,raw.time.output=TRUE)
