Description

Now that ARROW-2229 has been completed, we can wire up R to use the c++ bindings to write csvs from tables and record batches

https://github.com/apache/arrow/commit/9a9baf6824db91be2c0913367d4b151d9390a4e6#diff-d8b00a9202f9ae1ef6f2f113fec2e0f95f6287969317da520767738d690152d4R39-R44

There's a slight catch that it doesn't take shared_ptr so you have to *dereference them in the wrapper
