Sorting facets

[saslaw]

Hi, it is me again, thanks for your help last time! Is there any way to manually sort facets? I want to have them in a different order for a presentation slide, otherwise alphabetical usually makes sense. Here is what I have tried:

library(ggplot2)
library(ggh4x)

ggplot(mpg, aes(displ, hwy)) +
 geom_point() +
 facet_grid2(
   drv ~ .,
   scales = "free_y",
   cols = NULL,
   rows = vars(factor(drv, levels = c("r", "4", "f"))),
   space = "fixed",
   axes = "all",
   remove_labels = FALSE,
   independent = "y"
 ) +
 guides(x.sec = guide_axis(title = "displ"))
#> Error in !self$facet$shrink: invalid argument type

Is there a way to do it? Thank you again

Yeah, just leave out the drv ~. and it should work. Because you're using the rows argument already, the formula ends up in the next available argument, which is shrink, which doesn't accept formulas.
