pizza_estimate: Estimate your pizza order

In Chicago-R-User-Group/RUGtools: Functions useful for organizing R User Group meetups

Estimate your pizza order

Description

Function to compute how many pizzas to order based on arguments provided. Defaults to thin crust.

Usage

pizza_estimate(registered = 120, pizza_diameter = 18,
  attend_rate = 0.6, serving = 2, style = "thin")

Arguments

registered	Integer. The number of people registered on Meetup.com
pizza_diameter	Integer. Diameter of the largest pizza available in inches. Defaults to 18 inches for an extra large pizza.
attend_rate	Numeric of type double. The percentage estimate of attendance. Defaults to 60 percent attendance rate, expressed as 0.60.
serving	Integer or Numeric. Number of servings per person. Default is 2 and does not have to be a whole number. See references for methodology!
style	Character vector of either "thin", "pan", or "deepdish". Defaults to "thin" crust, please read the Details section for important information. Most pizza parlors have "thin" and "pan" styles..."deepdish" is an option because this function was written in Chicago, though it is our sincerest hope, that we shall never set this parameter.

Details

Chicago thin crust is cut into small squares, known as "tavern style" or "party cut".

Channeling our ever-curious pizza scientist, it turns out, the "party cut" inherits a few very attractive properties when dividing multiple pizzas among n guests. Smaller pieces allow guests to more precisely estimate pizza consumption, thus decreasing the integer-programming problem exacerbated by larger slices.

By requesting the "party cut", one reduces the tragedy that is wasted pizza and exhibits great stewardship of the sponsor resources entrusted to them.

Value

pizza_estimate returns a data.frame containing 5 variables. These are registered, est_attend, eaters_per_pizza, style, and the pizza_estimate.
