The {deflator} package is a demonstration of how to create a simple
package. It has one function, flate_gdp(), for inflating or deflating
UK prices by GDP. It also has one dataset, gdp_deflator, which is a
data frame of year-on-year inflation rates published on
GOV.UK.
You can install from github with:
