Thank you Hadley.

I've just discovered an another bug (perhaps ?) :

qplot(mpg, wt, data=mtcars)# works

qplot(mpg, wt, data=mtcars, geom = "line") # works

qplot(mpg, wt, data=mtcars) + facet_grid(cyl ~ vs) # works

qplot(mpg, wt, data=mtcars, geom = "line") + facet_grid(cyl ~ vs)
Erreur dans grobs[[i, j]] <- layer$make_grob(layerd[[i, j]], details, coord)
