#rstats filter_out is good

`dplyr::if_else()` and `dplyr::case_when()` are up to 30x faster dplyr 1.2.0 comes with much faster and more memory efficient `if_else()` and `case_when()` functions!

Last week we released dplyr 1.2.0, but we left off something VERY important 🙂

`dplyr::if_else()` and `dplyr::case_when()` are now up to 30x faster and use 10x less memory!

We dive into how we achieved these numbers in this new #rstats post!

Looks great @emilhvitfeldt.bsky.social ! Working on new tutorials at the moment, will have to try those out !

#rstats I've given a workshop a few days ago on handling large data (think tens to hundreds of millions of rows) with Polars in Python and in R.

Here are my introductory slides: brussels-large-data-r-python.etiennebacher.com

Just started reading the course materials from @physaliacourses.bsky.social on Genomic data (github.com/loukesio/dat...) by @bioinformatician.bsky.social, and already learned a couple valuable #tidyverse tricks!
- how to use "names_pattern" in pivot_longer()
- change labels using labeller()

{report} #rstats package version 0.6.2 is now on CRAN!

MANY bug fixes in this version! Including corrected duplicated text outputs and dramatic speed increases for brmsfit models (which used to refit the model entirely every time).

Doesn't look like ggplot2 to me :-) Well done!

I'm in the middle of preparing slides for an "Introduction to R" course. Thought I'd use a figure to explain element recycling in vectorized operations.

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up

There isn't a lot of new information yet, but this format allows me to add more easily
