Feature request: Added support of Arrow tables

[Ahschreyer]

Hello!

Is it possible to add conversions options of pandas/polars data-frames into R-Arrow tables?
And similarly from R-Arrow tables into PyArrow tables? Or from R-arrow to pandas/polars?

Conversion of R-Arrow tables to PyArrow tables would ideally enable "zero copy" of data between R and python. Similar to reticulate and rpy2-arrow.

R-Arrow tables are also easy to use along with dplyr, which can be extended to making graphs using ggplot2, so I am hoping this feature might be added.

Thanks for the suggestion! I designed ryp to use arrow as the backend but assumed most users wouldn't want to convert their own arrow objects. I'd be open to revisiting that assumption if there's more demand for it. That said, I just pushed some major changes to allow zero-copy of integer and floating-point data in to_r(), and also in to_py() in limited situations where it's safe. Hopefully this should make things much faster for your use-case of ggplot2 plotting!
