The art of the y axis

Just discovered {slider} package today, thanks to ChatGPT, perfect for window functions like rolling average and cumulative sums. Never underestimate how often these use cases come up in the business world. #rstats

I've always been using the second approach to select a few variables from df2, but discovered the trick of suffix = c("", ".df2") and all_of(names(df1)). #rstats

n8n 🤯🤯🤯

I was today years old when I discovered this trick in googlesheets4 📦: setting `reformat = FALSE` could preserve existing cell formatting! Every time I updated Google Sheets using range_write(), my formatting (e.g., numbers to currency) disappeared 😩. #rstats #googlesheets4
