Having trouble with ggplot2. It was working fine, but now I get this error message.
This example is using the ggplot2 bundled data set mpg, but I get the same message with any data set/code that I try.
Error in .standalone_types_check_dot_call(ffi_standalone_check_number_1.0.7, :
object 'ffi_standalone_check_number_1.0.7' not found
ggplot(mpg, aes(displ, hwy)) + geom_point()
