Example code stat_summary with fun.data does not return a result

[JoFAM]

When I run the following code from the help page of ?stat_summary():

d <- ggplot(mtcars, aes(cyl, mpg)) + geom_point()
d + stat_summary(fun.data = "mean_cl_boot", colour = "red", size = 2)

I don't see any summary stat displayed on the plot and I get following warning:

Warning message:
Computation failed in `stat_summary()`:

Never mind, it happens when the package Hmisc is not installed. Maybe that could be returned by the warning message :-)
