# fstplyr

[![Travis-CI Build Status](https://travis-ci.org/krlmlr/fstplyr.svg?branch=master)](https://travis-ci.org/krlmlr/fstplyr)

[![Coverage status](https://codecov.io/gh/krlmlr/fstplyr/branch/master/graph/badge.svg)](https://codecov.io/github/krlmlr/fstplyr?branch=master)

[![CRAN status](http://www.r-pkg.org/badges/version/fstplyr)](https://cran.r-project.org/package=fstplyr)

Provides a simple yet complete [dplyr](http://dplyr.tidyverse.org/) interface to [fst](http://www.fstpackage.org/) files. Currently only `select()` and `head()` make use of fst's superior performance, all other methods offload to the default data frame implementation. The data is always returned as a [tibble](http://tibble.tidyverse.org/).

## Example

```{r example}

path <- tempfile()

dir.create(path)

fst::write_fst(iris, file.path(path, "iris.fst"))

fst::write_fst(mtcars, file.path(path, "mtcars"))

library(fstplyr)

src <- src_fst(path)

src

tbl(src, "mtcars") %>%

  select(mpg:wt, -drat, gear)

```
