Quotes of the Week

Hear me, oh people! Stop using nested `ifelse()` functions and start using `dplyr::case_when()` !
It's easier AND faster! #rstatstwitter.com #tidyversetwitter.com ( twitter.com )

I was recently asked to give a stats talk in my department on how to analyse zero-inflated count data, which is a common problem in ecology (and especially behavioural ecology). I came up with this flowchart and thought I'd share it in case it's useful for any of you #rstatstwitter.com pic.twitter.com/8zhEzQFuIVt.co ( twitter.com )
