Example requires 'gridGraphics'

[MichaelChirico]

patchwork/man/wrap_elements.Rd

Lines 69 to 73 in 51a6eff

	# You can even add base graphics if you pass it as a formula
	p1 + wrap_elements(full = ~ plot(mtcars$mpg, mtcars$disp))
	# Adding a grob or formula directly is equivalent to placing it in `full`
	p1 + ~ plot(mtcars$mpg, mtcars$disp)

This example fails if gridGraphics is missing. Should we wrap the whole example in @examplesIf gridGraphics? Or perhaps it's better to note the requirement more explicitly:

# You can even add base graphics if you pass it as a formula (requires gridGraphics package)
if (requireNamespace("gridGraphics", quietly = TRUE)) {
  p1 + wrap_elements(full = ~ plot(mtcars$mpg, mtcars$disp))

  # Adding a grob or formula directly is equivalent to placing it in `full`
  p1 + ~ plot(mtcars$mpg, mtcars$disp)
}

yeah, last suggestion is good - would you like to make a PR?
