Error in skim_without_charts(penguins) :
could not find function "skim_without_charts"
skim_without_charts() seems to be a function in the skimr package. Have you run
library(skimr)
If that returns an error saying the package is not found, run
install.packages("skimr")
You only have to run installpackages() once. You have to run library(skimr) whenever you start R and want to use the package.
