Online vigntte error: geom_icon()

[ajlyons]

Thanks for a fantastic package. The sample code for geom_icon in the online Vignette is not working for me. I get the following error:

"Error in class(grobs) <- "gList" : attempt to set an attribute on NULL"

I suspect the icon names ('ios-power', 'ios-wifi', 'ios-pie') in the code snippet are no longer available on https://ionicons.com/. If you change those to valid icon names, it works.
