#AdventOfCode Day 08 - both parts using igraph! #rstats igraph is superspeedy. pivot_wider() is slow, which to be fair creates 1k columns so that I can get the pairings. Will be a better way, but I was keen to get to igraph asap. First for loop this year 😀 (but I failed Day 03 and skipped Day 04).

My original solution now solves Part II for Test data 😅 1.25 stars in total I award myself for Day 07 🤩

Fixed it!!! With just distances() instead of all simple paths. I tried this earlier too only for the splitters in the last low. Running it on all splitters was the trick 😅 Now on to Part II, which surely requires all paths and therefore can’t be done with my love of graphs? #rstats

Distances function instead of all simple paths

#AdventOfCode Day 07 Part I & Test data only Can I please get 0.25 ⭐ for solving it for the test input, but running out of memory for the real input 😅

#AdventOfCode Day 06 - both parts 🥳💃 Knew I wanted to do today's in #rstats instead of #pydata as soon as I saw it. Nice wrangling. Some duplication in code, but don't have time to reduce. Pun intended.

#AdventOfCode Day 02 Part I only. Not sure I could do Part II even if I was using beloved #rstats, and not struggling through with #pydata. Anyway, tomorrow is another day. Happy to do what I can given the time restrictions that I have 🚸

It's most wonderful time of the year - #AdventOfCode Day 01🎄 Having abandoned #pydata in favour of #rstats 13 years ago, I am keen to give our relationship another go. Especially as I left pre-pandas 🐼 Will revert to R as soon as the going gets tough. Probably in a day or two 😅

#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 🥳🎄

#AdventOfCode Day 06 in #rstats and #tidyverse Again just Part I, don't even have time to read the instructions for Part II 😅🎄

#AdventOfCode Day 05 in #rstats and #tidyverse 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 😅

#AdventOfCode 2024, Day 03 in #rstats and #tidyverse 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.

#AdventOfCode 2024, Day 02 in #rstats and #tidyverse 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 🥳

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 Full example: www.riinu.me/2024/02/cons... #rstats

#AdventOfCode #rstats Day 07 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()
