Read and write feather files.

Usage

read_feather(path, columns = NULL, ...)

write_feather(x, path, version = 1, ...)

Arguments

path: Path to feather file
columns: Columns to read (names or indexes), or a tidy selection specification of columns, as used in dplyr::select(). Default: Read all columns.
...: Additional arguments passed to the arrow:: functions
x: A data frame to write to disk
version: integer in c(1, 2) indicating the Feather format version to write. For compatibility, the default for feather::write_feather() is 1.

Value

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

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