rainbowR meet-up: Wednesday August 27th, 4pm UTC
- connect with other LGBTQ+ people who code in #RStats 
- ask questions about R 
- tell us about an R package you like 
- show us something R-related you’ve been working on 
Registration via rainbowr.org/meetups
Sometimes you get data in less than optimal format, e.g. as a png of a figure 
... In that case https://cran.r-project.org/web/packages/metaDigitise/vignettes/metaDigitise.html might be the rescue. #rstats #ohno #datawrangling
The {huxtable} #RStats is for “creating text tables. It is powerful, but easy to use. Huxtable’s features include:
* Export to LaTeX, HTML, Microsoft Word, Microsoft Excel, Microsoft Powerpoint, RTF and Markdown
* Easy integration with knitr and rmarkdown documents”
By David Hugh-Jones. On CRAN.

Ever wonder how an actuary becomes a data science educator? 
Tune into the latest episode of The Test Set with @minecr. We discuss everything from her journey to her innovative use of LLMs to give students immediate feedback on their code.
Listen at https://thetestset.co, Apple Podcasts, or Spotify.

Here I tend to read a lot of negative comments about #LLMs, but does anyone share my experience? I use them as an aid to mostly write #rstats and #LaTeX #tikz code faster or recently to clean up a very messy #emacs configuration file. They may hallucinate and I always need to double check the output, but I find #LLMs extremely useful. The ecological footprint is a discussion for another day.
today's adventures with #rstats and #targets, a thread:
Some time ago, I learned (from @nrennie ) that you could set up an assignment with the question(s) and solution(s) in one Quarto file, using a parameter called `hide_answers` in the yaml header that is either true or false (details below), and then render that file once with `hide_answers` being true (to get just the questions, and once with it being false (to get the solutions as well). Today I learned about `targets::tar_quarto_rep`.
Free #book alert
As #health #tech and #policy assessment graduates from proprietary spreadsheet apps (like #Microsoft #Excel) to open, generalizable, and powerful systems like #Rstats, a generation of researchers need to retool.
This book is for them: https://gianluca.statistica.it/books/online/r-hta/
I now also have a (work in progress) list of #DataViz specific resources as well!
Link: https://nrennie.rbind.io/data-viz-resources/
You can find links to tools, papers, books, blogs, and websites that are related to data visualisation. I'll be adding more resources soon 
It's #TidyTuesday y'all! Show us what you made on our Slack at https://dslc.io/join (find the #chat-tidytuesday channel)!

Next week, on August 19th, #RLang #RStats has a R Contribution Working Group ("fostering a larger, more diverse community of contributors to R core development") meeting
https://fosstodon.org/@HeathrTurnr/115017072820315500
which could be an opportunity to ask what next steps need to happen to move forward on @HeathrTurnr 's draft Code of Conduct question https://github.com/r-devel/rcwg/issues/34
[edited to correct which meeting would be a productive one for this particular question, and to fix wording on current CoC status]
@yabellini Thank you for your work! Looking forward to digging into the speech.
People in #rstats #rlang reading this thread may be interested in my post https://harihareswara.net/posts/2024/double-standards-and-volunteer-behavior/ spurred by a conversation last year. R folks were reporting difficult experiences uploading packages to the package repository (CRAN), especially because of one particular long-timer volunteer in R.

#RStats Dev Diary: PDF encoding
PDFs can use ASCII85 encoding as an efficient (but uncommon) binary-to-text encoding.
* hexadecimal: 1 byte = 2 chars. 50% efficiency
* base64: 3 bytes = 4 characters. 75% efficiency
* Ascii85: 4 bytes = 5 characters. 80% efficiency
Wrote an ascii85 encoder/decoder in vanilla R to help with PDF creation: https://github.com/coolbutuseless/minipdf/blob/430e0bb4e8348404b029c78f34516ca02420ff25/R/filters.R#L108

We explored how Communities of Practice help us learn, grow, and shape the R programming language. All my examples comes feom @rOpenSci but we also mencioned @RLadiesGlobal, @thecarpentries and other R-related communities

I had the honor of giving a keynote at #useR2025 
at Duke University: “We R Together – How to learn, use, and improve a programming language as a community”

Find the best contrast between one color and a list of options, e.g. for labels in geom_tile: {prismatic::best_contrast()} https://emilhvitfeldt.github.io/prismatic/reference/best_contrast.html #rstats #dataviz #ggplot #colors
#RStats hive mind:
What do you use if you want to encode binary data to hexadecimal string representation?
E.g. bytes<1, 255, 10>
=> "01ff0a"
Make sure to take the time to come to this tutorial by Mitchell O’Hara-Wild all about time series analysis. Learn how to use the tidyverse to manipulate time series data and the fable ️ to create models in a timely fashion.
