meedr

The goal of meedr is to provide quick and easy access to market expectations data to the main macroeconomic indicators in the Focus report, made available by the Central Bank of Brazil through the Expectations System data API. This data comes from several financial institutions, such as: banks, brokers, funds, consultancies, etc.

The meedr package offers an R interface to the API and other advantages:

• Use of a caching system with package memoise to speed up repeated requests of data;
• User can utilize all cores of the machine (parallel computing) when fetching a large batch of time series.

Check the meedr pkgdown page for more general information ;)

Example

These are some basic examples of using the package:

get_monthly()

library(meedr)

# Monthly market expectations for IPCA indicator
ipca <- meedr::get_monthly(
  indicator      = "IPCA",
  first_date     = Sys.Date()-30,
  reference_date = format(Sys.Date(), "%m/%Y"),
  be_quiet       = TRUE
  )

head(ipca, 5)

#> # ... with 2 more variables: n_respondents <int>, basis <int>

get_quarterly()

# Quarterly market expectations for GDP indicator
meedr::get_quarterly(
  indicator      = "PIB Total",
  first_date     = "2021-01-01",
  reference_date = paste0(lubridate::quarter(Sys.Date()), "/", lubridate::year(Sys.Date())),
  be_quiet       = TRUE
  )

get_annual()

# Annual market expectations for SELIC and exchange rate (BRL) indicator
meedr::get_annual(
  indicator      = c("Meta para taxa over-selic", "Taxa de câmbio"),
  reference_date = format(Sys.Date(), "%Y"),
  be_quiet       = TRUE
  )

get_inflation_12m()

# Inflation over the next 12 months
# First, and a suggestion, run this for using parallel computing:
future::plan(future::multisession, workers = floor(future::availableCores()/2))
meedr::get_inflation_12m(
  indicator   = c("IGP-DI", "IGP-M", "INPC", "IPA-DI", "IPA-M", "IPCA", "IPCA-15", "IPC-FIPE"),
  smoothed    = "yes",
  be_quiet    = FALSE, # display messages
  do_parallel = TRUE # turn on parallel computing
  )

get_monthly_top5()

# Monthly market expectations for IGP-M indicator (Top 5 Focus)
meedr::get_monthly_top5(
  indicator  = "IGP-M",
  first_date = NULL, # get all data to current date
  calc_type  = "long",
  be_quiet   = TRUE
  )

get_annual_top5()

# Annual market expectations for SELIC indicator (Top 5 Focus)
meedr::get_annual_top5(
  indicator   = "Meta para taxa over-selic",
  detail      = "Fim do ano",
  be_quiet    = TRUE,
  use_memoise = FALSE # disable caching system
  )
