[![DOI](https://joss.theoj.org/papers/10.21105/joss.02800/status.svg)](https://doi.org/10.21105/joss.02800)R interface to the [Data Retriever](https://retriever.readthedocs.io/en/latest/).
The `rdataretriever` provides access to cleaned versions of hundreds of commonly used public datasets with a single line of code.
These datasets come from many different sources and most of them require some cleaning and restructuring prior to analysis.
The `rdataretriever` uses a set of actively maintained recipes for downloading, cleaning, and restructing these datasets using a combination of the [Frictionless Data Specification](https://specs.frictionlessdata.io/) and custom data cleaning scripts.The `rdataretriever` also facilitates the automatic storage of these datasets in a choice of database management systems (PostgreSQL, SQLite, MySQL, MariaDB) or flat file formats (CSV, XML, JSON) for later use and integration with large data analysis pipelines.
The `rdatretriever` also facilitates reproducibile science by providing tools to archive and rerun the precise version of a dataset and associated cleaning steps that was used for a specific analysis.
The `rdataretriever` handles the work of cleaning, storing, and archiving data so that you can focus on analysis, inference and visualization.

The `rdataretriever` is an R wrapper for the Python package, [Data Retriever](https://retriever.readthedocs.io/en/latest/). This means
that *Python* and the `retriever` Python package need to be installed first.### Basic Installation
If you just want to use the Data Retriever from within R follow these
instuctions run the following commands in R. This will create a local Python
installation that will only be used by R and install the needed Python package
for you.```coffee
install.packages('reticulate') # Install R package for interacting with Python
reticulate::install_miniconda() # Install Python
reticulate::py_install('retriever') # Install the Python retriever package
install.packages('rdataretriever') # Install the R package for running the retriever
rdataretriever::get_updates() # Update the available datasets
```**After running these commands restart R.**
### Advanced Installation for Python Users
If you are using Python for other tasks you can use `rdataretriever` with your
existing Python installation (though the [basic installation](#basic-installation)
above will also work in this case by creating a separate miniconda install and
Python environment).#### Install the `retriever` Python package
Install the `retriever` Python package into your prefered Python environment
using either `conda` (64-bit conda is required):```bash
conda install -c conda-forge retriever
```or `pip`:
```bash
pip install retriever
```#### Select the Python environment to use in R
`rdataretriever` will try to find Python environments with `retriever` (see the
`reticulate` documentation on
[order of discovery](https://rstudio.github.io/reticulate/articles/versions.html#order-of-discovery-1)
for more details) installed. Alternatively you can select a Python environment
to use when working with `rdataretriever` (and other packages using
`reticulate`).The most robust way to do this is to set the `RETICULATE_PYTHON` environment
variable to point to the preferred Python executable:```coffee
Sys.setenv(RETICULATE_PYTHON = "/path/to/python")
```This command can be run interactively or placed in `.Renviron` in your home
directory.Alternatively you can do select the Python environment through the `reticulate`
package for either `conda`:```coffee
library(reticulate)
use_conda('name_of_conda_environment')
```or `virtualenv`:
```coffee
library(reticulate)
use_virtualenv("path_to_virtualenv_environment")
```You can check to see which Python environment is being used with:
```coffee
py_config()
```#### Install the `rdataretriever` R package
```coffee
install.packages("rdataretriever") # latest release from CRAN
``````coffee
remotes::install_github("ropensci/rdataretriever") # development version from GitHub
```## Installing Tabular Datasets
```coffee
library(rdataretriever)# List the datasets available via the Retriever
rdataretriever::datasets()# Install the portal into csv files in your working directory
rdataretriever::install_csv('portal')# Download the raw portal dataset files without any processing to the
# subdirectory named data
rdataretriever::download('portal', './data/')# Install and load a dataset as a list
portal = rdataretriever::fetch('portal')
names(portal)
head(portal$species)```
## Installing Spatial Datasets
**Set-up and Requirements**
**Tools**
- PostgreSQL with PostGis, psql(client), raster2pgsql, shp2pgsql, gdal,
The `rdataretriever` supports installation of spatial data into `Postgres DBMS`.
1. **Install PostgreSQL and PostGis**
To install `PostgreSQL` with `PostGis` for use with spatial data please refer to the
[OSGeo Postgres installation instructions](https://trac.osgeo.org/postgis/wiki/UsersWikiPostGIS21UbuntuPGSQL93Apt).We recommend storing your PostgreSQL login information in a `.pgpass` file to
avoid supplying the password every time.
See the [`.pgpass` documentation](https://wiki.postgresql.org/wiki/Pgpass) for more details.After installation, Make sure you have the paths to these tools added to your system's `PATHS`.
Please consult an operating system expert for help on how to change or add the `PATH` variables.**For example, this could be a sample of paths exported on Mac:**
```shell
#~/.bash_profile file, Postgres PATHS and tools.
export PATH="/Applications/Postgres.app/Contents/MacOS/bin:${PATH}"
export PATH="$PATH:/Applications/Postgres.app/Contents/Versions/10/bin"```
2. **Enable PostGIS extensions**
If you have `Postgres` set up, enable `PostGIS` extensions.
This is done by using either `Postgres CLI` or `GUI(PgAdmin)` and run**For psql CLI**
```shell
psql -d yourdatabase -c "CREATE EXTENSION postgis;"
psql -d yourdatabase -c "CREATE EXTENSION postgis_topology;"
```**For GUI(PgAdmin)**
```sql
CREATE EXTENSION postgis;
CREATE EXTENSION postgis_topology
```
For more details refer to the
[PostGIS docs](https://postgis.net/docs/postgis_installation.html#install_short_version).**Sample commands**
```R
rdataretriever::install_postgres('harvard-forest') # Vector data
rdataretriever::install_postgres('bioclim') # Raster data# Install only the data of USGS elevation in the given extent
rdataretriever::install_postgres('usgs-elevation', list(-94.98704597353938, 39.027001800158615, -94.3599408119917, 40.69577051867074))```
## Provenance
To ensure reproducibility the `rdataretriever` supports creating snapshots of the data and the script in time.
Use the commit function to create and store the snapshot image of the data in time. Provide a descriptive message for the created commit. This is comparable to a git commit, however the function bundles the data and scripts used as a backup.
With provenace, you will be able to reproduce the same analysis in the future.
**Commit a dataset**
By default commits will be stored in the provenance directory `.retriever_provenance`, but this directory can be changed by setting the environment variable `PROVENANCE_DIR`.
```coffee
rdataretriever::commit('abalone-age',
commit_message='A snapshot of Abalone Dataset as of 2020-02-26')
```You can also set the path for an individual commit:
```coffee
rdataretriever::commit('abalone-age',
commit_message='Data and recipe archive for Abalone Data on 2020-02-26',
path='.')
```**View a log of committed datasets in the provenance directory**
```coffee
rdataretriever::commit_log('abalone-age')
```**Install a committed dataset**
To reanalyze a committed dataset, rdataretriever will obtain the data and script from the history and rdataretriever will install this particular data into the given back-end. For example, SQLite:
```coffee
rdataretriever::install_sqlite('abalone-age-a76e77.zip')
```
Datasets stored in provenance directory can be installed directly using hash value
```coffee
rdataretriever::install_sqlite('abalone-age', hash_value='a76e77')
```## Using Docker Containers
To run the image interactively
`docker-compose run --service-ports rdata /bin/bash`
To run tests
`docker-compose run rdata Rscript load_and_test.R`
Release
-------Make sure you have tests passing on R-oldrelease, current R-release and R-devel
To check the package
```Shell
R CMD Build #build the package
R CMD check --as-cran --no-manual rdataretriever_[version]tar.gz
```To Test
```R
