dplyr 1.2.0 was released last week and since I use {dplyr} a lot in my work, I wanted to take some time to try some of the new functions.

This post provides some supplemental examples of the new functions, beyond what is provided in the new Posit materials.

dplyr 1.2.0 is out now and we are SO excited!

- `filter_out()` for dropping rows

- `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools

These are huge quality of life wins for #rstats!

dplyr 1.2.0
dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

After years of working with Gifted dogs, this paper marks the end of that chapter for me 🐕

We compared gifted and typical dogs and found that what sets gifted dogs apart may not be curiosity, but their social motivation

Grateful to the dogs and their humans 💙

Do you use SEM because it looks cleaner?

SEM vs. SD = one of the most quietly damaging figure-making habits in biology

Let’s clear it up

You can specify relative position in ggplot with I(x) I(y).

E.g. annotate("text", x = I(.5), y = I(.5), label = "hello!") will place the text in the middle of the plot.
This, combined with alignment arguments is like 87% of the magic for me.

Adorable dog Zelda, dressed like Sherlock Holmes, gazes at the camera while lying next to a copy of DETECTIVE DOGS. In one paw, she holds a magnifying glass while three spotted lanternflies scurry across the floor in front of her. Outstanding Science Trade Book and Best STEM Book seals can be seen on the left.

Despite Prepublication Peer Review being a core part of science, training materials for it are sparse. This open source guide is very valuable for ECRs!
