multiQQPlot: multiQQPlot

In hutchisonjtw/JNCCTools: A Package to Store Useful Functions for JNCC Staff

Description

Plots quantile-quantile plots for multiple probability distributions on one set of axes.

Usage

multiQQPlot(x, main = "QQ plot of sample data against likely distributions",
  distr = c("nbinom", "pois", "norm", "lnorm"))

Arguments

x	Numeric vector of data values to be plotted to be plotted as a histogram.
main	Title for the plot. Default value is "QQ plot of sample data against likely distributions".
distr	Character vector of distributions for which to produce QQ plots. Note that this uses the standard R names for the distributions which differ from those used in emon. Should be one or more of "norm" (normal), "pois" (Poisson), "lnorm" (log normal) and "nbinom" (negative binomial). By default all four are plotted.

Details

QQ plots are used to visually assess how well a data sample fits a given probability distribution.

Value

Primarily used for plotting, but invisibly returns an object of class multiQQ, which can be stored for later plotting if required.
