Feature request - unique values #659

First of all, thank you for making this awesome useful package!

I use this almost every my data analysis nowadays! One thing that I want to have in the skim() function is to show the number of unique values for each variables. Can we have that in the future?

Thanks Issac!

We probably won't change the default summary functions for skimr any time soon, but one of the package's strengths is customization. For factors and character variables, we show a count of the highest frequency values: https://github.com/ropensci/skimr/blob/840b6237597e3da7c8970a6581086ef73c561678/R/stats.R#L65-L78

There a lot of examples for package customization in the README, vignettes and documentation for skim_with(). https://github.com/ropensci/skimr/blob/840b6237597e3da7c8970a6581086ef73c561678/R/skim_with.R#L40

Let us know if we can give more pointers.

Best wishes, Michael
