[PATCH] ggplot2: fix ggsave('a.svg').

[PATCH] ggplot2: fix ggsave('a.svg').

[Ben Woodcroft]

Hi all,

Beforehand, trying to save an SVG file from a plot generated with ggplot did
not work.  'r-svglite' is only a listed as a suggested dependency for gpglot2,
but given that saving SVGs is reasonably central (at least for me), then I
think we should propagate it.

Test code:
$ R
> library(ggplot2)
> qplot(x=c(1,2,3),y=c(3,4,6))
> ggsave('/tmp/a.svg')
Saving 6.99 x 7 in image

Thanks,
ben

Looks like this is indeed “GPLv3 only”.  The README states “The gdtools
package is licensed under the GPLv3.”

Without that notice it would have been GPLv3 or later, because that’s
how the license field in DESCRIPTION files is usually interpreted.

This patch looks good to me.  Thanks!

How about just “SVG graphics device”?

How about

    @dfn{SVG} (Scalable Vector Graphics)

?

The rest looks fine.

Thanks for the review. I pushed this set with both these changes.
