plot_lognormalvar: Plots a lognormal variable

In SAMtool: Stock Assessment Methods Toolkit

Plots a lognormal variable

Description

Plots the probability distribution function of a lognormal variable from the mean and standard deviation in either transformed (normal) or untransformed space.

Usage

plot_lognormalvar(m, sd, label = NULL, logtransform = FALSE, color = "black")

Arguments

m	A vector of means of the distribution.
sd	A vector of standard deviations of the distribution.
label	Name of the variable to be used as x-axis label.
logtransform	Indicates whether the mean and standard deviation are in lognormal (TRUE) or normal (FALSE) space.
color	A vector of colors.

Value

A plot of the probability distribution function. Vertical dotted line indicates mean of distribution. This function can plot multiple curves when multiple means and standard deviations are provided.

Examples

mu <- 0.5
stddev <- 0.1
plot_lognormalvar(mu, stddev) # mean of plot should be 0.5

#logtransformed parameters
mu <- 0
stddev <- 0.1
plot_lognormalvar(mu, stddev, logtransform = TRUE) # mean of plot should be 1
