EVPlot

Extreme value plot (frequency and growth curves)

Description

Plots the extreme value frequency curve or growth curve with observed sample points. With the option of generalised extreme value (GEV), generalised Pareto (GenPareto), or generalised logistic (GenLog) distributions.

Usage

EVPlot(
  x,
  dist = "GenLog",
  scaled = TRUE,
  Title = "Extreme value plot",
  ylabel = NULL
)

Arguments

`x`	a numeric vector. The sample of interest
`dist`	a choice of distribution. "GEV", "GenLog", or "GenPareto". The default is "GenLog"
`scaled`	logical argument with a default of TRUE. If TRUE the plot is a growth curve (scaled by the QMED). If FALSE, the plot is a frequency curve
`Title`	a character string. The user chosen plot title. The default is "Extreme value plot"
`ylabel`	a character string. The user chosen label for the y axis. The default is "Q/QMED" if scaled = TRUE and "Discharge (m3/s)" if scaled = FALSE

Value

An extreme value plot

Examples

#Get an AMAX sample and plot the growth curve with the GEV distribution
AM.203018 <- GetAM(203018)
EVPlot(AM.203018$Flow, dist = "GEV")
