extract_stats from grouped_* plots

[andreifoldes]

Greetings,

Could the extract_stats function be extended such that it can extract statistics according the grouping.var when used on grouped_* plots?

Yes, this is something I want to implement.

For now, have a look at the examples to see how this can be done, one plot at a time.

library(ggstatsplot)

p <- grouped_ggpiestats(mtcars, x = cyl, grouping.var = am)
extract_stats(p)
