deflate: Deflate Nominal Brazilian Reais Using Various Price Indexes

In deflateBR: Deflate Nominal Brazilian Reais

Description

deflate() uses data from the Brazilian Institute for Applied Economic Research's API (IPEADATA) to adjust nominal Brazilian Reais for inflation.

Usage

deflate(nominal_values, nominal_dates, real_date, index = c("ipca",
  "igpm", "igpdi", "ipc", "inpc"))

Arguments

nominal_values	A numeric vector containing nominal Brazilian Reais to deflate.
nominal_dates	A Date vector with corresponding nominal dates (i.e., when nominal values were measured). Values are set to the previous month, following the standard methodology used by the Brazilian Central Bank.
real_date	A value indicating the reference date to deflate nominal values in the format 'MM/YYYY' (e.g., '01/2018' for January 2018).
index	Indicates the price index used to deflate nominal Reais. Valid options are: ipca, igpm, igpdi, ipc, and inpc.

Details

Each one of the five price indexes included in the function are maintained by two Brazilian agencies: IPCA and INPC indexes are maintained by Brazilian Institute of Geography and Statistics (IBGE); IGP-M, IGP-DI, and IPC are maintained by Getulio Vargas Foundation (FGV). For an overview of the indexes' methodologies and covered periods, check the Brazilian Central Bank official FAQ.

Value

A numeric vector.

Examples

## Not run: 
# Use IPCA index to deflate a vector of nominal Brazilian Reais
reais <- rep(100, 5)
actual_dates <- seq.Date(from = as.Date("2001-01-01"), to = as.Date("2001-05-01"), by = "month")

deflate(reais, actual_dates, "01/2018", "ipca")

# Using IGP-M index
deflate(reais, actual_dates, "01/2018", "igpm")
