    TIL: I tend to forget that purrr's lambda notation conflicts w/ magrittr's lambda expression... 👌 purrr::map_dbl(1:10, ~ .x %>% sqrt) ☠️ purrr::map_dbl(1:10, ~ . %>% sqrt) 👌 purrr::map_dbl(1:10, . %>% sqrt)

    I'll be speaking at about a streamlined workflow for tidy time series analysis using tsibble and fable. A warm-up post to provide an overview of tsibble with a case study of NYC Citi bike data.

    performance tip: if you must grow a vector in a loop, make sure there's only one reference to it so that R doesn't have to make a copy on each iteration. # 6 seconds: x <- integer() for(i in 1:5e4) x <- c(x, i) # 0.02 seconds: x <- integer() for(i in 1:5e4) x[i] <- i

    My new favorite (and probably overused) party trick is to use knitr::include_url("link_to_my_own_slides") to show a past/future slide FROM THE SAME slide deck in another slide 🤯 Makes it easier to show how to do side-by-side code/plot slides.

    Why you should only ever bake with weights

    My son was asking about the definition of "1 cup" in a recipe and good grief it's bonkers. So: in the US, volume measures are based on the gallon, which is the volume of a cylinder 6 inches high and 7 inches in diameter, rounded to the nearest cubic inch.

    🎄3 in 1 🎄 praise is a great 📦 for brightening up an day ☀️ rep(praise, 5) only gives us one type of praise - it evaluates before repeating. replicate(5, praise) gives us 5 different types of praise - it re-evaluates each time 🤫 secretly it's sapply 🤫

    Monday morning hot take - I find opinionated style guides to be a much easier way for me to get up to speed on new languages than reference materials, language specs, or tutorials. Eg, The tidyverse style guide for R
