cpi_inflator_quarters(from_nominal_price, from_qtr, to_qtr,
  adjustment = c("seasonal", "trimmed", "none"), useABSConnection = FALSE)

Arguments

from_nominal_price

(numeric) the nominal prices to be converted to a real price

from_qtr

(date in quarters) the dates contemporaneous to the prices in from_nominal_price. Must be of the form "YYYY-Qq" e.g. "1066-Q2". Q1 = Mar, Q2 = Jun, Q3 = Sep, Q4 = Dec.

to_qtr

(date in quarters) the date to be inflated to, where nominal price = real price. Must be of the form "YYYY-Qq" e.g. "1066-Q2".

adjustment

Should there be an adjustment made to the index? Adjustments include 'none' (no adjustment), 'seasonal', or 'trimmed' [referring to trimmed mean]. By default, seasonal.

useABSConnection

Should the function connect with ABS.Stat via an SDMX connection? By default set to FALSE in which case a pre-prepared index table is used. This is much faster and more reliable (in terms of errors), though of course relies on the package maintainer to keep the tables up-to-date. The internal data is up-to-date as of 2017-Q4. If using useABSConnection = TRUE, ensure you have rsdmx (>= 0.5-10) up-to-date.

Value

A vector of real prices.
