There's a few rules I've adopted for data analysis this year that have helped me out a lot.

If you have R students learning to clean data, the truffle package by Ian Hussey (
@ianhussey.mmmdata.io
) might be for you. Plus the icon is a cute pig 🐷

Thanks, Nur Shahir, for the tip! www.linkedin.com/in/nmshahir/

Maybe you're interested in trying {renv} for creating reproducible environments for your R projects. Maybe you've tried and it hasn't stuck. Shannon's talk digs deep into how it works so it's easier to implement.
this talk is for frustrated {renv} users and potential {renv} users

Ever run `install.packages()` and wish it were faster, smarter, and more reliable?

The {pak} package speeds things up with parallel downloads, dependency solving, and reproducible installs.

Ever need to count the number of characters in a variable (sometimes based on a pattern)? The #rstats {stringr} package is great for that. ✨
cghlewis.github.io/data-wrangli...
d11 # A tibble: 4 x 2 id item1 <dbl> <chr> 1 1 "cap" 2 2 "ap" 3 3 "" 4 4 "p" In this data, item1 represents student responses of a word. Each letter represents a correct phonetic sound. We want to count the number of correct sounds for each student. We first create a new variable item1_score using dplyr::mutate(). We can then use stringr::str_length() to count the length of our strings. d11 %>% dplyr::mutate(item1_score = stringr::str_length(item1)) # A tibble: 4 x 3 id item1 item1_score <dbl> <chr> <int> 1 1 "cap" 3 2 2 "ap" 2 3 3 "" 0 4 4 "p" 1 d12 # A tibble: 4 x 2 id item1 <dbl> <chr> 1 1 "c,a,p" 2 2 "a,p" 3 3 "" 4 4 "p" Same as above, item1 represents student responses of a word. Each letter represents a correct phonetic sound. We want to count the number of correct sounds for each student. However, this time, our data has commas between letters so we cannot use stringr::str_length() because it will count the commas, giving us incorrect scores. Instead we use stringr::str_count() and add the argument pattern = and we add the regex pattern “[a-z]” which says to count any lowercase letter a to z. d12 %>% dplyr::mutate(item1_score = stringr::str_count(item1, pattern = "[a-z]")) # A tibble: 4 x 3 id item1 item1_score <dbl> <chr> <int> 1 1 "c,a,p" 3 2 2 "a,p" 2 3 3 "" 0 4 4 "p" 1

🧵Hi #RLadies and R friends! Have you built a package?

I started writing my own functions when I noticed I was copying the same code over and over. Eventually, I wrapped some of them into a package — just for myself.

Now I’m learning how to turn my code into tools others can actually use. 📦💜

Screenshot showing Firefox browser displaying a webR REPL interface in the foreground, with an RStudio session visible in the background. The webR interface shows decoded R files (main.R, functions.R, config.R, sample_data.csv) that were embedded in a shareable URL. The RStudio console in the background displays the encoded webR sharelink URL that packages all the local files. On the right side, R documentation is open showing help for the 'Create WebR REPL sharelink for multiple files' function. This demonstrates the workflow of encoding local R project files into a URL that can be shared and automatically reconstructed in a browser-based R environment.

It's a lightweight #Rstats 📦 to draw beautiful and complex plots, using an ultra-simple and concise syntax.

This is a massive release! @gmcd.bsky.social @zeileis.org and I worked hard to add tons of new themes and plot types.

Check it out!

TidyTuesday featuring Purple, Green, Brown, Pink, Blue "waffles" of different hexes. Most of the guesses are accurate but some seem a bit humorously incorrect.

Ending the week with a #TidyTuesday plot 🎨

Visualised the top 100 colours from the XKCD colour survey - colour names + hex codes in a swatch view.

Made with R and a bit of Patrick Hand font fun.
