The tidyverse is a miniature ecosystem within R which has certain coding conventions and tooling to make certain data analysis easier and prettier.

Most lucid explanation of everything is Hadley Wickham’s Advanced R book which is free and only“Advanced” in the sense that your knowledge of R will be advanced after reading it, not in the sense of being forbiddingly complicated for beginners.

Others:

• purr

A FP package for R in the spirit of underscore.js.

(You may or may not consider that statement snark)

• magrittr brings a compose (“pipe”) operator to R, which looks like this: %>%. Here is a tutorial clarifyin why this is useful

Useful functions: semi_join etc.

## The tidyverts

The time-series tidyverse is the tidyverts incorporating time series dataframs, generic mostly-linear prediction and explorations. You can find a presentation on them by Rob Hyndman.

## Reshaping

The names have changed and I need to document. spread, gather, pivot_wide, pivot_long etc.
