--------------------------------------
Summary: [R] Add our philosophy to the dev vignette
Key: ARROW-14441
URL: https://issues.apache.org/jira/browse/ARROW-14441
Project: Apache Arrow
Issue Type: Improvement
Components: R
Reporter: Jonathan Keane
This isn't necessarily limited to CSVs, but we should have this philosophy in
our developing vignette
The general approach we've done with CSV things in the past is:
(1) support the readr signature to the best extent we can, translating to the
arrow parameter names internally;
(2) allow someone to pass the arrow options (CsvReadOptions etc.) directly, in
case they want to do things at a lower level
(3) where necessary add extra args to the readr signature for features that
don't exist in R but do in arrow (e.g. schema)
This is our general philosophy: present things to the R user in a way that is
least surprising to them (most follows R conventions) and also provide access
to all of Arrow's features (sometimes that's extra args, sometimes it's the
arrow_ prefixed functions in dplyr, sometimes it's just the lower-level R6
objects and methods that more closely follow the C++ interface)
