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.
write_to_raw(x, format = c("stream", "file"))
x:
data.frame, RecordBatch, or Table
format:
one of c("stream", "file"), indicating the IPC format to use
A raw vector containing the bytes of the IPC serialized data.
# The default format is "stream" mtcars_raw <- write_to_raw(mtcars)
