multipdf_plot: multipdf_plot

In ztils: Various Common Statistical Utilities

multipdf_plot

Description

This function extends 'multiPDF_cont' and gets the probability density functions (PDFs) for selected distributions against continuous variables. Possible distributions include any combination of "normal", "lognormal", "gamma", "exponential", and "all" (which just uses all of the prior distributions). It then plots this using 'ggplot2' and a 'scico' palette, using var_name for the plot labeling, if specified. If not specified, it will use var instead.

Usage

multipdf_plot(
  var,
  seq_length = 50,
  distributions = "all",
  palette = "oslo",
  var_name = NULL
)

Arguments

var	The variable to for which to plot PDFs
seq_length	The number of points over which to fit x
distributions	The distributions to fit x against
palette	The color palette to use on the graph
var_name	The variable name to use for x. If no name is provided, the function will grab the column name provided in x

Value

A plot showing the PDF of the selected variable against the selected distributions over the selected sequence length

Examples

multipdf_plot(iris$Sepal.Length)

multipdf_plot(iris$Sepal.Length,
              seq_length = 100,
              distributions = c("normal", "lognormal", "gamma"),
              palette = "bilbao",
              var_name = "Sepal Length (cm)"
              )
