> 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.
