> [R] Minimum working example round-tripping a data frame from R to plasma to
> pandas
> ----------------------------------------------------------------------------------
>
> Key: ARROW-3205
> URL: https://issues.apache.org/jira/browse/ARROW-3205
> Project: Apache Arrow
> Issue Type: New Feature
> Components: R
> Reporter: James Lamb
> Priority: Minor
>
> I see tremendous opportunity for interoperability between Python and R (two
> popular languages for data scientists) using Arrow as an interchange format.
> To make this concrete and get developers in those languages interested, I
> think it would be valuable to create a minimum working example of writing an
> R data frame into plasma and reading it back up into *pandas* in a separate
> Python process, and vice versa.
> I could, for example, envision reading a CSV up into a *data.table* in R to
> do some cleaning and feature engineering, writing that object to *plasma*,
> then kicking off multiple parallel Python processes to search a space of
> models. This could demonstrate the benefits of replacing "load this dataset
> from a file 50 times" with "read off this range of memory in plasma".
>
> I believe pretty strongly that a tangible example like this would
> meaningfully improve the R community's interest in and engagement with the
> Arrow project.
