Quickly plot probability density function

Description

Quickly plot probability density function

Usage

plot_pdensity(
  fun,
  x = NULL,
  color = "skyblue",
  linetype = "solid",
  size = 1.5,
  fill = NA,
  alpha = 0.3,
  location = 0,
  p_limit = 0.001,
  lower_bound = -10000,
  upper_bound = 10000,
  ...
)

Arguments

fun	A probability density function (e.g. dnorm).
x	(Optional) A sequence of values for the probability density function. If not supplied, the function will be plotted for all points with probability density greater than p_limit (default 0.001) between the lower_bound (default -10000) and the upper_bound (default 10000).
color	The color of the plotted line (default "skyblue").
linetype	The linetype (default "solid").
size	The size of the line (default 1.5).
fill	The color of the fill under the line (default NA = no fill)
alpha	The alpha transparency for the fill (default 0.3).
location	For probability density functions that do not have a location parameter, this will shift the center (zero) of that distribution to the specified location.
p_limit	The probability density cutoff for plotting.
lower_bound	The (potential) lower range of plotting subject to the p_limit cutoff (default -10000).
upper_bound	The (potential) upper range of plotting subject to the p_limit cutoff (default 10000).
...	Any additional parameters will be passed to the probability density function

Value

A ggplot gg object.

Examples

plot_pdensity(dnorm)
plot_pdensity(dnorm, seq(-3, 3, length.out = 100))
plot_pdensity(dbeta, shape1 = 2, shape2 = 2)
