umxPlotFun: Easily plot functions in R

In umx: Structural Equation Modeling and Twin Modeling in R

Easily plot functions in R

Description

A wrapper for ggplot2::stat_function() that handles single or multiple functions.

Usage

umxPlotFun(
  fun = c("sin(x)", "cos(x)"),
  min = -1,
  max = 5,
  xlab = NULL,
  ylab = NULL,
  title = NULL,
  logY = c("no", "log", "log10"),
  logX = c("no", "log", "log10"),
  p = NULL
)

Arguments

fun	Function(s) to plot. Takes strings like c("3 + sin(x)^2", "cos(x)") or function objects.
min	x-range min.
max	x-range max.
xlab	Optional x axis label.
ylab	Optional y axis label.
title	Optional title for the plot.
logY	Set to "log" or "log10" to transform y coordinate.
logX	Set to "log" or "log10" to transform x coordinate.
p	Optional plot onto which to draw the function(s).

Details

Easily plot functions—like sin or x^2—using ggplot. Accepts bare functions, strings, or lists of strings/functions. Automatically generates a legend when multiple functions are provided.

Value

A ggplot graph object
