Small multiples

Show the same kind of plot for each group. Keeping the scales fixed lets readers compare levels across panels without adjusting for different axes.

Usage

facet_tufte(facets, ncol = NULL, nrow = NULL, scales = "fixed", ...)

Arguments

facets

Variables to facet by, as with facet_wrap(), for example vars(cyl) or ~ cyl.

ncol, nrow

Panel layout. ncol defaults to NULL, letting ggplot2 choose.

scales

Passed to facet_wrap(). Defaults to "fixed", and warns if you change it, because free scales make panels incomparable.

...

Further arguments passed to facet_wrap().

Value

A ggplot2 facet specification.

Details

This wraps facet_wrap() with fixed scales and left-aligned, unboxed strip labels. ggplot2 chooses the layout unless you specify it. Free scales can help with other questions, but they make comparisons of levels harder, so the function warns when you request them.

Examples

library(ggplot2)
ggplot(mtcars, aes(wt, mpg)) +
  geom_point() +
  geom_rangeframe() +
  facet_tufte(~ cyl) +
  theme_tufte()
