inconsistency in print.ggplot documentation

[r2evans]

?ggplot2::print.ggplot currently includes:

Value:

     Invisibly returns the result of 'ggplot_build()', which is a list
     with components that contain the plot itself, the data,
     information about the scales, panels etc.

but the code itself is returning invisible(x), not invisible(data) (where data <- ggplot_build(x)).

If I am interpreting this correctly, then an easy fix might be from:

1. Change the documentation from result of 'ggplot_build()' to the original plot; or
2. Change from invisible(x) to invisible(data).

(Personally I prefer the second, but that might be a breaking change and require more changes than just one line, e.g., testing and/or notification of a future breaking change.)

I'm willing to submit a PR for this if there is interest.

Thanks for catching this - we should update the documentation to reflect how it is currently. I'll be happy to review a PR

That's too bad: I have a clone of this function that returns invisible(data) instead, I was hoping you'd side with that :-)
