Oh man, where do I even begin? Error in add_ggplot(e1, e2, e2name) : could not find function "is.coord" Error in (function (el, elname) : "panel.ontop" is not a valid theme element name... Error in layer(mapping = structure(list(x = element$Line, y = 0, xend = element$Line, : unused arguments (arrow = NULL, lineend = "butt", na.rm = FALSE, colour = "grey50", linetype = 2) Error : Unknown parameters: guides Error in FUN(X[[i]], ...) : attempt to apply non-function Error in coord_tern() : could not find function "coord" I just can't keep up with this - most of these errors are with objects I am not using (such as 'panel.ontop' when using theme(legend.position="bottom"). For those of us who chose (made the mistake?) of using ggplot2 with larger projects such as shiny, large updates like this which render all our past code mute presents a dilemma - do we keep re-learning this wheel or just stop updating altogether? The latter seems to be the only feasible course. Every plot implementation I had on my website was broken by this update. I don't mean to be mean, ggplot2 is a wonderful package, but this update presented all headaches.
