# Write Arrow data to a raw vector

<div class="ref-description section level2">

`write_ipc_stream()` and `write_feather()` write data to a sink and
return the data (`data.frame`, `RecordBatch`, or `Table`) they were
given. This function wraps those so that you can serialize data to a
buffer and access that buffer as a `raw` vector in R.
