Quotes of the Week

An Rstudio shortcut everybody should know is Alt + Shift to create a multiline cursor. Huge time saver for code formatting! #rstats pic.twitter.com/s9EQMRk8kT

#Rstats: Repeated measures ANOVA is traditionally a horrible nightmare in R. The `afex` package changes this. Easily specify a rm-model that gives identical results to SPSS using `afex::aov_car`. Automatically applies the GG correction.

Does anyone else have an #rstats thing (or things) they have to Google literally every time, even though they use it a lot? ???? ???? ???? I probably use this at least once a month and it still won't stick pic.twitter.com/nWpJfbnfne
