Lines 382 to 386 in b5b603a

	#' * `rel_min_height` Lines with heights below this cutoff will be removed. The cutoff is measured relative to the
	#' overall maximum, so `rel_min_height=0.01` would remove everything that is 1\% or less than the highest point among all
	#' ridgelines. Default is 0, so nothing is removed.
	#' alpha
	#' * `colour`, `fill`, `group`, `alpha`, `linetype`, `size`, as in [`geom_ridgeline`].

The 1\% doesn't render properly (write 1 percent?) and the alpha needs to be deleted.
