In NINAnor/NIcalc: Functions to Calculate a Nature Index

Plot function for known distributions

Description

Plot function for known distributions, defined by input parameters

Usage

plotDistribution(
  distrib = c("Gamma", "ZIExponential", "LogNormal", "TruncNormal", "Weibull"),
  mu = NULL,
  sig = NULL,
  refValue = 1,
  obsval = c(lower = NULL, mu = NULL, upper = NULL),
  type = "continuous"
)

Arguments

distrib	Type of distribution. Must match allowed values.
mu	first parameter of distribution
sig	second parameter of distribution
refValue	reference value to be plotted along with the distribution
obsval	double, length = 3, observed mean and quartiles in the sequence c(lower.quartile, mean, upper.quartile)
type	fixed parameter set to "continuous"

Note

In it's present form plotDistribution covers the Gamma- lognormal, truncated normal, Weibull and ZIExponential distributions. It may be expanded to cover more distributions and to accept other parameters than expected values and quartiles in obsval.
