Details

This is a cleaned subset of palmerpenguins::penguins.

Replicating this dataset:

require(palmerpenguins)
d <- palmerpenguins::penguins
d <- d[complete.cases(d), ] ## Remove missing, 2 obs of numeric and several in sex
d <- d[, c(3:6, 1, 7, 2)]   ## Numeric to front, group factors, remove year
penguins_na.rm <- as.data.frame(d) ## Remove {tibble} dependency
## save(penguins_na.rm, file = "./data/penguins_na.rm.rda")
