• Add an image to a Gist here: drop and drag the image into a comment on the gist, copy the generated code (there's no need to actually publish the comment).
• Compare two commits: github.com//<repo_name>/compare/...

This is a complete, step-by-step tutorial showing how to create a fully functional contact form in production in rails 5. Rather than reinvent things, the following borrows from the best available documentation and tutorials (most notably, this tutorial on making a contact form in development).

Question: Does paragraph length follow a normal distribution?

Many naturally occurring things follow a normal distribution.

I'm curious to know if paragraphs follow a normal distribution too?

Note: paragraph length could be measured in characters, or words.

Here we find world population by timezone (from an extremely reliable source: an online quiz).

First, we can try using rvest to grab the results. But there's a problem, we need to actually play the quiz in order for the UTC offsets to appear on page.

i.e.

library(tidyverse)
library(rvest)

# init.R
#
# Example R code to install packages if not already installed
#

my_packages = c("tidyverse", "shiny")

install_if_missing = function(p) {
  if (p %in% rownames(installed.packages()) == FALSE) {
    install.packages(p)
