Style

This is a style guide to writing documentation for arrow.

Coding style

Please use the tidyverse coding style.

Referring to external packages

When referring to external packages, include a link to the package at the first mention, and subsequently refer to it in plain text, e.g.

• “The arrow R package provides a dplyr interface to Arrow Datasets. This vignette introduces Datasets and shows how to use dplyr to analyze them.”

Data frames

When referring to the concept, use the phrase “data frame”, whereas when referring to an object of that class or when the class is important, write data.frame, e.g.

• “You can call write_dataset() on tabular data objects such as Arrow Tables or RecordBatches, or R data frames. If working with data frames you might want to use a tibble instead of a data.frame to take advantage of the default behaviour of partitioning data based on grouped variables.”
