In kjhealy/demog: Some demographic data

demog

Some demographic data, for teaching purposes. Please do not distribute this package. For the original mortality data, consult http://mortality.org and follow the instructions there.

Installation

demog is a data package.

Install direct from GitHub

You can install the beta version of demog from GitHub with:

devtools::install_github("kjhealy/demog")

Installation using drat

While using install_github() works just fine, it would be nicer to be able to just type install.packages("demog") or update.packages("demog") in the ordinary way. We can do this using Dirk Eddelbuettel's drat package. Drat provides a convenient way to make R aware of package repositories other than CRAN.

First, install drat:

if (!require("drat")) {
    install.packages("drat")
    library("drat")
}

Then use drat to tell R about the repository where demog is hosted:

drat::addRepo("kjhealy")

You can now install demog:

install.packages("demog")

To ensure that the demog repository is always available, you can add the following line to your .Rprofile or .Rprofile.site file:

drat::addRepo("kjhealy")

With that in place you'll be able to do install.packages("demog") or update.packages("demog") and have everything work as you'd expect.

Note that the drat repository only contains data packages that are not on CRAN, so you will never be in danger of grabbing the wrong version of any other package.

Loading the data

The package works best with the tidyverse libraries.

library(tidyverse)
