plot_t_dist: Plot one or more t-distributions

In michaelfrancenelson/mfn.teaching.utils:

Plot one or more t-distributions

Description

Shows the shape of different t-distributions with differing degrees of freedom. Can also include a plot of the normal as a reference.

Usage

plot_t_dist(
  df,
  xlim = c(-3, 3),
  n_x = 500,
  col = rep(1, length(df)),
  xlab = "",
  ylab = "Probability Density",
  main_fmt = "Degrees of Freedom = %d",
  hl_y = 0.05,
  hl_lty = 3,
  hl_col = 2,
  oma = c(0, 0, 0, 0),
  mar = c(3, 4, 2, 0.5),
  ylim = c(0, 0.4),
  norm = TRUE,
  col_norm = 2,
  lty_norm = 2,
  ...
)

Arguments

df	either a single value or a vector of degrees of freedom to plot
xlim	limits of the x-values to plot
n_x	how many points to simulate. Larger number = smoother curve
col	colors for the t curves
xlab	x-axis label
ylab	y-axis label
main_fmt	main title formatter
hl_y	height of the horizontal line to draw
hl_lty	type of horizontal line
hl_col	color for horizontal line
oma	outer margin
mar	main figure margins
ylim	y-limits for plotting
norm	should the standard normal be plotted as a reference?
col_norm	color for normal line
lty_norm	line style for normal
