# arrow
[](https://anaconda.org/conda-forge/r-arrow)
R integration with Apache Arrow.
## Installation
You first need to install the C++ library:
### macOS
On macOS, you may install using homebrew:
```
brew install apache-arrow
```
### From source
First install a release build of the C++ bindings to arrow.
```shell
git clone https://github.com/apache/arrow.git
cd arrow/cpp && mkdir release && cd release
# It is important to statically link to boost libraries
cmake .. -DARROW_PARQUET=ON -DCMAKE_BUILD_TYPE=Release -DARROW_BOOST_USE_SHARED:BOOL=Off
make install
```
## Then the R package
### From github (defaults to master branch)
```r
library("devtools")
devtools::install_github("apache/arrow/r")
```
## Example
```{r}
library(arrow)
(tib <- tibble::tibble(x = 1:10, y = rnorm(10)))
tab <- table(tib)
tab$schema
tab
as_tibble(tab)
```
## Developing
The arrow package is using devtools for package related manipulations. To install:
```r
library.packages("devtools")
```
Within a local clone, one can test changes by running the test suite.
### Running the test suite
```r
library("devtools")
devtools::install_dev_deps()
devtools::test()
```
### Full package validation
```shell
R CMD build --keep-empty-dirs .
R CMD check arrow_*.tar.gz --as-cran --no-manual
```
