Publication-ready tables! How cool is it to run code and instantly generate a fully formatted table! With flextable, you can: 🖍️ Style fonts 🔗 Merge cells 📑 Add layered headings 📐 Adjust dimensions Learn more in the EpiRHandbook: epirhandbook.com/en/new_pages... #rstats #epi

Day 8: Heatmaps! Epicurves are great when you have a few areas. But for dozens or hundreds of categories, if you want to see patterns then heatmaps are the way to go! epirhandbook.com/new_pages/he...

Day 9: Where do R version names come from? The current version is 4.4.2: Pile of Leaves. Check yours by running R.version on your console. Internet chat suggests these names are all inspired by the Peanuts comic. And sure enough… #r #rstats #charliebrown #peanuts 🥜

Day 10: Code readability! Are you making life harder for yourself in R? Or are you using rainbow parentheses and highlighted functions!? Which one does your code look like?

To enable these features, go to your Global Options, Code, and tick these two boxes under ‘Syntax’. Happy coding! #rstats #lifehacks #epi #r

🎄Day 11 🎄: Multi-panel figures! The R package {patchwork} makes professional-looking multi-panel figures like this SUPER easy to do. This means more efficient story telling, saved space, and clearer comparisons between groups. #r #dataviz #epi #rstats

🎄Day 12: Missing data🎄 Epis know well that missingness can skew analyses, so needs careful review. {naniar} can help! E.g.: ☑️pct_miss_case(): to check % of rows with NAs ☑️gg_miss_var(): to visualize missingness by column See more: Ch. 20 of the EpiRHandbook.com!

🎄Day 14: Quiz!🎄 Why do these two seemingly identical characters not equal each other in R?

🎄Day 17: RStudio magic🎄 Want to be in multiple places at once over the holidays? We can't help with that. But - we can show you how to type in multiple places at once in RStudio! 😮 Useful for making the same edit across your code, when Find + Replace isn't suitable.

🎄Day 20: Ggplot efficiency: part 2 🎄 Visualizing the same variables in different ways (e.g. sex by time/place)? 💡Tip: Easily standardize colour palettes by defining them once at the start of your code. Then reuse the palettes within scale_fill/color_manual() across plots

🎄Day 21: Ggplot efficiency part 3 🎄 Need many plots with the same style/formatting but slightly different inputs? 💡Create a custom ggplot function! Define your plot upfront in the function. Then run the function for each new plot with different inputs.

🎄Day 22: An R Christmas Tree 🎄 There's still time to write your Christmas cards! And what better captures the yuletide spirit than...R... Seriously though, check out the {christmas} package by Jose Barrera-Gomez (Jose Barrera). Stunning!

Today's post is for anyone with bdays this time of the year. Including our Exec Director, an expert in "combo Xmas/bday" presents! Happy birthday Neale! On that note, ever work with multiple date columns but need to pick one? Use coalesce() to easily prioritize a value! #Rstats

Ho ho ho Merry Christmas!
