Closes #21. Closes #72.

Examples

I use the one-sided formula method for the below examples. But the atomic method (e.g., plt(Nile, type = "histogram")) works just the same.

Standard histogram

plt(~Petal.Length, iris, type = "hist") # "hist" is alias for "histogram"

Question: I haven't switched off the surrounding plot frame (box) by default. Should we do this to make it more consistent with base hist()?

plt(~Petal.Length, iris, type = "hist", frame = FALSE)

Grouped histograms

plt(~Petal.Length | Species, iris, type = "hist")

Question: By default, the fill of grouped histograms is solid. Should we rather enable automatic alpha fill transparency for these (see next examples)?

Aside: We can adjust the number of breaks by passing a breaks argument.

plt(~Petal.Length | Species, iris, type = "hist", fill = 0.5, breaks = 30)

Grouped and faceted histograms

We could also facet by itself (i.e., no colour grouping), although I don't show that here.

plt(~Petal.Length | Species, iris, type = "hist", fill = 0.5, breaks = 30, facet = "by")

Again, we haven't turned off the frame by default but we might want to...

plt(~Petal.Length | Species, iris, type = "hist", fill = 0.5, breaks = 30, facet = "by", frame = FALSE)

More elaborate example where we use different (colour) groups and facets.

iris2 = iris |>
  transform(long_sepal = Sepal.Length > mean(Sepal.Length))
plt(~Petal.Length | Species, iris2, type = "hist", fill = 0.5, breaks = 30, facet = ~long_sepal)
