Right to left direction and alignment in ggplot2 charts

rtl_ggplot.R

library(ggplot2)

ggplot() + 
   ggtitle(label = "הסימן הזה הפוך!", 
           subtitle = "\u202bאבל דווקא זה בסדר!") + 
   theme(plot.title = ggplot2::element_text(hjust = 1), 
         plot.subtitle = ggplot2::element_text(hjust = 1))

just noticed - obviously once loaded library(ggplot2) you don't need the ggplot2::element_text(...), just use element_text(...).
