new ggplots exts

[omarbenites]

Hello Daniel, These are my ggexts packages to add:

1. gganimate: Create easy animations with ggplot2 Github Repo: https://github.com/dgrtwo/gganimate
2. sjPlot: ggplot exts for Data Visualization for Statistics in Social Science Github Repo: https://github.com/sjPlot/devel Examples and Documentation http://strengejacke.de/sjPlot/

I wouldn't call sjPlot a ggplot2 extension package. It's basically a bunch of functions building on top of ggplot2, and while I like an use them regularly, they don't provide any new geoms, scales or whatever in a way the new extensions building on top of ggplot2 2.0 do.

It is, however, extraordinarily useful.

I agree with @jemus42 , since many actual ggplot2 extensions are being submitted, let's reserve that space for them. Thanks though @omarbenites , I had never heard of "sjPlot" and now am dying to explore it.

Thanks @omarbenites . I have added gganimate.

Yep. Probably it's an useful tool for ggplot, but not exactly a ggplot extension. On the other hand (if it is possible), I think would be a good idea create a topic for ggplot wrappers (like sjPLot). Thanks @Emaasit, it's a really good work
