read_feather: Read and write feather files.

In feather: R Bindings to the Feather 'API'

Description

Read and write feather files.

Usage

read_feather(path, columns = NULL)

write_feather(x, path)

Arguments

path	Path to feather file
columns	Columns to read (names or indexes). Default: Read all columns.
x	A data frame to write to disk

Value

Both functions return a tibble/data frame. write_feather invisibly returns x (so you can use this function in a pipeline).

Examples

mtcars2 <- read_feather(feather_example("mtcars.feather"))
mtcars2
