tinyplot (version 0.4.1)

type_function: Plot a function

Description

Plot a function

Usage

type_function(fun = dnorm, args = list(), n = 101, ...)

Arguments

fun

Function of x to plot. Defaults to dnorm.

args

List of additional arguments to be passed to fun.

n

Number of points to interpolate on the x axis.

...

Additional arguments are passed to the lines() function, ex: type="p", col="pink".

Details

When using type_function() in a tinyplot() call, the x value indicates the range of values to plot on the x-axis.

Examples

# Plot the normal density (default function)
tinyplot(x = -4:4, type = "function")
# tinyplot(x = -4:4, type = type_function()) # same

# Customize by passing explicit arguments to your function
tinyplot(x = -1:10, type = type_function(
  fun = dnorm, args = list(mean = 3)
))

# Additional arguments are passed to the `lines()` function.
tinyplot(x = -4:4, type = type_function(
  fun = dnorm,
  col = "pink", type = "p", pch = 3
))

# Custom function example
## (Here using `function(x)`, but you could also use the shorter `\(x)`
## anonymous function syntax introduced in R 4.1.0)
tinyplot(x = -4:4, type = type_function(fun = function(x) 0.5 * exp(-abs(x))))
