📢Accurate != precise📢

Not precise, but accurate is also known as roughly right - Figure (a).

Not accurate, but precise is also known as precisely wrong - Figure (d).

#AdventOfCode Day 11 in #rstats and #tidyverse

Part II runs 3x faster than Part I 😉

First time using memoise although that's not the speed-up, as using that in both parts. Even the compulsive R-Restarter that I am (command+shift+R), it still bit me a few times 😂

Coding is joy 🥳🎄

Again just Part I, don't even have time to read the instructions for Part II 😅🎄

Part I only - probably won't have time for Part II.

Broke out crossing() for the first time this year - another function I only use in December 🙃

Part II is much better than Part I. Which is unusual 😅

fill() probably the most useful function here. First time using co-pilot, it was very helpful with the first regular expression, but weirdly lost the plot when I asked for the second one.

I wish I could say no for loops were harmed in solving today's puzzle...but I can't. I briefly envisioned something with maps and filters, but this is probably easier to read and understand.

Having fun either way 🥳

Hmmm....a bit early for having to bring in rowwise(), but it's done.

Patient flow (CONSORT) diagrams in R using library(consort) now easier than ever. Thanks Alim Dayim!

🤩 neat syntax
🔢 takes patient-level data
🖼️exports well to Word/PDF/PNG
✍️ a few options: number of side boxes, arms, font size

Not bad this one. Part II: first got right answer for test, but wrong for real input. Issue was mishandling of the 5-joker hand.

MVP: using a named vector in str_replace_all()
