Usage
Load the package:
library(rbcb)The get_series function
Download the series by calling
rbcb::get_series and pass the time series code is as the first
argument. For example, let’s download the USDBRL time series which code
is 1.
rbcb::get_series(c(USDBRL = 1))
#> # A tibble: 9,434 x 2
#> date USDBRL
#> <date> <dbl>
#> 1 1984-11-28 2828
#> 2 1984-11-29 2828
#> 3 1984-11-30 2881
#> 4 1984-12-03 2881
#> 5 1984-12-04 2881

#> 9 1984-12-10 2965
#> 10 1984-12-11 2965
#> # ... with 9,424 more rowsNote that this series starts at 1984 and has approximately 8000 rows.
Also note that you can name the downloaded series by passing a named
vector in the code argument. To download recent values you should
use the argument last = N, see below.
rbcb::get_series(c(USDBRL = 1), last = 10)
#> # A tibble: 10 x 2
#> date USDBRL

#> 9 2022-07-22 5.45
#> 10 2022-07-25 5.41 The series can be downloaded in many
different types: tibble, xts, ts or data.frame, but the default
is tibble. See the next example where the Brazilian Broad Consumer
Price Index (IPCA) is downloaded as xts object.
rbcb::get_series(c(IPCA = 433), last = 12, as = "xts")

The function
get_market_expectations returns market expectations discussed in the
Focus Report that summarizes the statistics calculated from expectations
collected from market practitioners.
The first argument type accepts the following values:
annual: annual expectationsquarterly: quarterly expectationsmonthly: monthly expectationstop5s-monthly: monthly expectations for top 5 indicatorstop5s-annual: annual expectations for top 5 indicatorsinflation-12-months: inflation expectations for the next 12 monthsinstitutions: market expectations informed by financial institutions
The example below shows how to download IPCA’s monthly expectations.

its own currency name.

Cross currency rates
The API provides a matrix with the relations between exchange rates, this is the matrix of cross currency rates. This is a square matrix with the all exchange rates between all currencies.

dim(x)
#> [1] 156 156# Since there are many currencies it is interesting to subset the matrix.
cr <- c("USD", "BRL", "EUR", "CAD")

#> USD 1.0000000 3.1623 0.9380896 1.3465764

#> CAD 0.7426240 2.3484 0.6966479 1.0000000The rates are quoted by its columns labels, so the numbers in the BRL column are worth one currency unit in BRL.
