I did not find anything on how the weight aesthetic in geom_boxplot / stat_boxplot is working. Is it missing? Or did I look at the wrong place?

  p1 <- ggplot(mpg, aes(class, hwy)) + geom_boxplot(),
  p2 <- ggplot(mpg, aes(class, hwy)) + geom_boxplot(aes(weight=displ))
cbind(ggplot_build(p1)$data[[1]][,"middle"], ggplot_build(p2)$data[[1]][,"middle"])

It weights the computation of the quantiles.

@hadley I read several plot codes with the weight aesthetic, but I still couldn't figure out how this aesthetic works exactly. So could you explain it more specifically or point where the weight aesthetic's source code lies? Thx : )
