**odbr** is an R package to download data from Brazil’s Origin
Destination Surveys. The package provides databases, maps, and data
dictionaries in English, Portuguese, and Spanish. Furthermore, it is
possible to download harmonized data across different cohorts for the
same city.

## Installation

You can install the [odbr
Package](https://CRAN.R-project.org/package=odbr) with:

``` r
# install from CRAN
install.packages("odbr")
library(odbr)
```

You can install the development version of odbr from
[GitHub](https://github.com/) with:

``` r
# or use the development version with latest features
devtools::install_github("hsvab/odbr")
library(odbr)
```

## Basic Usage

The syntax of all `odbr` functions operate on the same logic so it
becomes intuitive to download any data set using a single line of code.
Like this:

``` r
# Return data from OD Surveys database as data.frame
library(odbr)

df <- read_od(
  city = "Sao Paulo",
  year = 2017,
  harmonize = FALSE
)
#> Downloading file to: /tmp/RtmpjicoRU/od_sao_paulo_2017_not_harmonized.csv.gz

# Return zone data from OD Surveys database as sf object at a given city and year
df <- read_map(
  city = "Sao Paulo",
  year = 2017,
  harmonize = FALSE,
  geometry = "zone"
)
#> Downloading file to: /tmp/RtmpjicoRU/zone_sao_paulo_2017_not_harmonized.gpkg

# Return data dictionary from OD Surveys, as data.frame, at a given city and year
df <- read_dictionary(
  city = "Sao Paulo",
  year = 2017,
  harmonize = FALSE,
  language = "pt"
)
```

## Available datasets:

**The original geodetic reference system remained unchanged.**

| City      | Years available              | Harmonized | Dictionary languages | Source                                                                             |
| --------- | ---------------------------- | ---------- | -------------------- | ---------------------------------------------------------------------------------- |
| São Paulo | 1977, 1987, 1997, 2007, 2017 | No         | en, es, pt-br        | [Metrô-SP](https://transparencia.metrosp.com.br/dataset/pesquisa-origem-e-destino) |

**There is no harmonized data available yet.**

*All harmonized datasets use geodetic reference system “SIRGAS2000”,
CRS(4674).*

Champions Program (2022 edition) whose main goal is to provide support
to R developers from around the world who identify themselves as members
of groups that are systematically excluded from the open-source software
community.
