Load the package:
library(rbcb)
The get_series function
<a name="single-series"></a> 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
#> 6 1984-12-05 2923
#> 7 1984-12-06 2923
#> 8 1984-12-07 2923
#> 9 1984-12-10 2965
#> 10 1984-12-11 2965
#> # ... with 9,424 more rows
Note 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.
<a name="tibble-objects"></a>
rbcb::get_series(c(USDBRL = 1), last = 10)
#> # A tibble: 10 x 2
#> date USDBRL
#> <date> <dbl>

<a name="download-types"></a> 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.
<a name="xts-objects"></a>
rbcb::get_series(c(IPCA = 433), last = 12, as = "xts")
#> IPCA
#> 2021-07-01 0.96

or as a ts object.

<a name="multiple-series"></a> Multiple series can be downloaded at once by passing a named vector with the series codes. The return is a named list with the downloaded series.
rbcb::get_series(c(IPCA = 433, IGPM = 189), last = 12, as = "ts")
