## Overview
Haven enables R to read and write various data formats used by other
statistical packages by wrapping the fantastic
[ReadStat](https://github.com/WizardMac/ReadStat) C library written by
[Evan Miller](http://www.evanmiller.org). Haven is part of the
[tidyverse](http://tidyverse.org). Currently it supports:
- **SAS**: `read_sas()` reads `.sas7bdat` + `.sas7bcat` files and
`read_xpt()` reads SAS transport files (version 5 and version 8).
- **SPSS**: `read_sav()` reads `.sav` files and `read_por()` reads the
older `.por` files. `write_sav()` writes `.sav` files.
- **Stata**: `read_dta()` reads `.dta` files (up to version 15).
`write_dta()` writes `.dta` files (versions 8-15).
The output objects:
- Are [tibbles](http://github.com/hadley/tibble), which have a better
print method for very long and very wide files.
- Translate value labels into a new `labelled()` class, which
preserves the original semantics and can easily be coerced to
factors with `as_factor()`. Special missing values are preserved.
See `vignette("semantics")` for more details.
- Dates and times are converted to R date/time classes. Character
vectors are not converted to factors.
## Installation
``` r
# The easiest way to get haven is to install the whole tidyverse:
install.packages("tidyverse")
# Alternatively, install just haven:
install.packages("haven")
# Or the the development version from GitHub:
# install.packages("devtools")
devtools::install_github("tidyverse/haven")
```
## Usage
``` r
library(haven)
# SAS
read_sas("mtcars.sas7bdat")
write_sas(mtcars, "mtcars.sas7bdat")
# SPSS
read_sav("mtcars.sav")
write_sav(mtcars, "mtcars.sav")
# Stata
read_dta("mtcars.dta")
write_dta(mtcars, "mtcars.dta")
```
