plotGamma {LearningStats}

Density Function, Distribution Function and/or Quantile Function Representations associated with a Gamma Distribution

Description

plotGamma represents density, distribution and/or quantile functions associated with a Gamma distribution with certain parameters lambda and shape.

Usage

plotGamma(lambda, shape, type = "b", col = "black")

Arguments

lambda, shape

parameters of the Gamma distribution (mean equal to shape/lambda).

type

a character string giving the type of desired plot. The following values are possible: "b" (default) for density function, distribution function and quantile function representations together, "dis" for distribution function representation, "den" for density function representation and "q" for quantile function representation.

col

a single colour associated with the different representations; default to "black".

Value

This function is called for the side effect of drawing the plot.

Examples

lambda=0.5;shape=4
plotGamma(lambda,shape)
plotGamma(lambda,shape,col="red")
plotGamma(lambda,shape,type="q")
plotGamma(lambda,shape,type="dis")
plotGamma(lambda,shape,type="den")
