Wrangling data in JavaScript with Arquero: a primer for R users Quick compare: tidyverse & Arquero side-by-side If you're familiar with wrangling data using tidyverse functions in R, the Arquero library by Jeffrey Heer provides similar verbs for essential cleaning...

I do! Here are some I made specifically with #rstats folks in mind:

A cute round monster, smiling while skating on a frozen pond in a winter snowscape with frosty pine trees. The skate tracks reveal what developers hope for in package checks: "0 warnings, 0 errors, 0 notes."

Cartoon split screen, on the left a demoralized zombified data scientist fails to write code at 5pm Friday, needing a serious break. On the right, they've woken up and look totally refreshed and happy at 6am on Saturday, the scene now looking delightful.

Cartoon monsters dressed as characters from "It." Pennywise holds balloons, one with the Microsoft Teams logo on it, while peering out from a storm drain while another little monster in a raincoat looks on.

I recently had the opportunity to interview Ben Welsh (Reuters news applications editor), during a very interesting time for data journalists. Check out the story below! ๐Ÿ‘‡

Trump victory has sweeping climate change consequences From the endorsement of climate denial to a brain drain of climate scientists, Trump's victory will bring major changes.

I'm a climate scientist living in Texas who served as a lead author on the National Climate Assessment under the previous Trump administration. I witnessed first-hand its chilling impact on access to data, funding & publication of research, implementation of solutions, and scientists themselves. ๐Ÿงต

An illustration recreating the It movie poster, where a monster version of Pennywise peers out of a storm drain holding red balloons and hex stickers, enticing a little monster in a yellow raincoat who looks on. On the balloons are written different things to be cautious about in R / stats. On the raincoat are different hex stickers (for janitor, naniar, usethis, dplyr, renv...).

๐Ÿ‘ป Here's the โœจ new 2024 art, feat. community responses to the question "What's something in R that feels tempting, but is actually dangerous?"

I couldn't fit them all, so I've added a blank version ๐Ÿ‘‡๐Ÿงต so you can make your own (could be a fun class activity ๐Ÿ˜‰)

Happy Halloween, #rstats world! ๐Ÿคก๐ŸŽˆ

Small fuzzy R monsters in costume as famous villains from horror movies. Left to right: Chucky (wearing a wig, rainbow shirt and overalls, with stitches on its face), the girl from The Ring (black long hair over face), Hannibal Lecter (masked with bars in front of mouth), and Jason (iconic hockey mask). On the wall behind them are different menacing tools (butcher knives, saws, scythe) with scary things on them, e.g. "Can't automatically merge," "screenshot error message," "no such file or directory", "$ operator is invalid for atomic vectors."
