draw a normal distribution with beautiful illustrations

This was developed for the R Working Example collection in my website, https://pj.freefaculty.org/R/WorkingExamples

Usage

drawnorm(
  mu = 0,
  sigma = 1,
  xlab = "A Normally Distributed Variable",
  ylab = "Probability Density",
  main,
  ps = par("ps"),
  ...
)

Arguments

mu

The mu parameter

sigma

The sigma parameter

xlab

Label for x axis

ylab

Label for Y axis

main

Title for plot. OK to ignore this, we'll make a nice one for you

ps

pointsize of text

...

arguments passed to par

Examples

drawnorm(mu = 10, sigma = 20)

drawnorm(mu= 0, sigma = 1)

drawnorm(mu = 102, sigma = 313)

drawnorm(mu = 0, sigma = 1, main = "A Standard Normal Distribution, N(0,1)",
         xlab = "X", ylab = "Density", ps = 7)

drawnorm(mu = 0, sigma = 1, ylab = "Density", ps = 14)
