Description

For consistency, it seems like it would be useful to have it behave in a similar manner to read.delim(), read_tsv(), etc...

Ex:

 

library(feather)
library(tidyverse)
options(stringsAsFactors = FALSE)

write_tsv(head(iris), 'test.tsv')
write_feather(head(iris), 'test.feather')

head(read.delim('test.tsv', sep='\t')$Species)
# [1] "setosa" "setosa" "setosa" "setosa" "setosa" "setosa"

head(read_tsv('test.tsv', col_types = cols())$Species)
# [1] "setosa" "setosa" "setosa" "setosa" "setosa" "setosa"

head(read_feather('test.feather')$Species)
# [1] setosa setosa setosa setosa setosa setosa
# Levels: setosa versicolor virginica

 

Versions:

• R 3.6.2

• feather 0.3.5
