Research direction
The issue names no page or file, so first find the existing extendr docs that cover converting R vectors to Rust types. Read the linked extendr PR #1006 to confirm how BTreeSet<&str> and HashSet<&str> are built via TryFrom from Strings, and how Option<&str> handles NA. Done when a short section with a small example and an NA note is added and the site builds locally.
Written by the indexing model from the issue text.
Description
https://github.com/extendr/extendr/pull/1006/ introduced support for using BTreeSet<&str> and HashSet<&str> via TryFrom &Strings
This is useful for getting a set of unique values from an R vector. Use Option<&str> for handling NAs the former will error when using NAs in the string.
