Setting the last plot in the middle with facet_wrap

I am trying to create some multiplots with facet_wrap. However I am not sure if is the right approach for my graph. Here is a short reproducible example:

 ggplot(airquality, aes(x = Day, y = Temp)) +
  facet_wrap(~Month) + 
  geom_line()

This produces this plot here:

Is it possible to "center" the two plots in the 2nd row with the facet_wrap approach ?

Note, that I don't want to reorder the plots, I just want to Center the 2nd row

Solution

  • @Tjebo's suggestion of using cowplot will work:

    p <- ggplot(mapping = aes(x = Day, y = Temp)) +
  facet_wrap(~Month) + 
  geom_line()

cowplot::plot_grid(
  p %+% subset(airquality, Month < 8),
  p %+% subset(airquality, Month > 7),
  nrow = 2
)
