facet_grid() facet labels cannot be rotated when switched from right to left

Updated

strip.text.y.left is not documented. This issue becomes a documentation one.

Original issue raised:

When facet labels are on the right, they can be rotated:

d2 <- diamonds[sample(seq_len(nrow(diamonds)), 1000), ]
ggplot(d2) +
  geom_point(aes(carat, price)) +
  facet_grid(vars(cut), vars(color)) +
  theme(strip.text.y = element_text(angle = 0))

Now add switch = 'y' to facet_grid() and the facet labels are not rotated anymore.

ggplot(d2) +
  geom_point(aes(carat, price)) +
  facet_grid(vars(cut), vars(color), switch = 'y') +
  theme(strip.text.y = element_text(angle = 0))

If this is possible, then I can move the facet labels to the left and move the y-axis to the right. I want the facet labels to be horizontal so that they are easier to read.

you need to use :
theme(strip.text.y.left = element_text(angle = 0))

Thanks @certara-smouksassi . I didn't know strip.text.y.left exists; it's not in the documentation. Perhaps this issue becomes a documentation one.
