Clarify that span is only used for loess in stat_smooth

[nalimilan]

It can be surprising that span argument has no effect when number of observations is large (cf. #3174).

You need to edit the original text and then re-generate the docs by devtools::document().

ggplot2/R/stat-smooth.r

Lines 26 to 28 in a132727

	#' @param span Controls the amount of smoothing for the default loess smoother.
	#' Smaller numbers produce wigglier lines, larger numbers produce smoother
	#' lines.

Ah of course, sorry!

Thanks, almost looks good to me! I added minor comments about spacing.

One more thing, Tidyverse team is trying to change the license of ggplot2 to more permissive one (the MIT license) to minimize the problems and confusions arising from license incompatibilities. If you are fine that your contribution will be merged to ggplot2 and get licensed under MIT, would you mind commenting "I agree" on #4231?

For more details, you can join the discussion on #4236, or wait for their upcoming blog post.
