map of the 2025 New York City mayoral race, using different colors to represent the three main candidates

politics aside, it's pretty amazing to find high quality data visualizations for free on the Wikipedia page for the recent NYC mayoral election. and using a clever ternary plot to represent the breakdown of votes for three candidates in one color

yes yes! thanks for sharing your Libby fact. also, jetpens is indeed the best. I thought about a side project of scraping all their fountain pens and visualizing all the dimensions of pens (sizes, color, etc). never did, but I still think of it from time to time 😅

maybe I'll add it to the Christmas wish list 😂

a fellow stationary and pens nerd! I got a retractable fountain pen for my birthday and it is just the best. I've seen this pen advertised to me, but I keep on telling myself I have enough pens 🥲 so tempting!

i guess they could be useful to be consistent with specifying different quotes, instead of remembering which quotes need to be escaped etc.

either way, it's a "the more you know" kind of thing built into R

recently learned the sQuote() and dQuote() R functions

> cat("distinguish plain", sQuote("single"), "and", dQuote("double"), "quotes")
distinguish plain ‘single’ and “double” quotes
> cat("distinguish between 'single' and \"double\" quotes")
distinguish between 'single' and "double" quotes

If you ask me for advice, the answer I give you will almost always be to reach out and talk to people. Not to read blog posts or watch youtube videos, though those are wonderful resources, but to meet with & talk to actual humans. It's not easy, and it takes time and effort, but it's the way #databs

Keyboard shortcuts for Visual Studio Code Here you will find the complete list of keyboard shortcuts for Visual Studio Code and how to change them.

been trying to get into using vscode a bit more, and had some of the keyboard shortcuts interfere with each other.

took me a bit to figure it out, but in case anyone else is having issues with it, go to File > Preferences > Keyboard Shortcuts menu

tryCatch block in R, change value of outer variable Here is my code. It produces infinite loop, because value of something variable does not change within captured error. Is it supposed to be this way? How can I fix it so that value of something cha...

turns out, tryCatch() in R is locally scoped, so if you need to change any variables, you'll need to make it more explicit with something like

assign("var_i_need_to_change", "change_to_this_value", env = globalenv())

woah, when did RStudio gain this functionality that when you wait for autocomplete to finish, it'll show you a preview of that data object that it is suggesting in the autocomplete?? #RStats

very cool! didn't know of this package. might be useful after training indeed. yeah, my problem is on the training side of things. thanks for sharing!

oh interesting, I could give it a try and see. thanks for pointing this out! wasn't aware of them nor noticed them in the documentation
