geom_mosaic's alpha clashes with psych's alpha

[Rmadillo]

If you have psych loaded (which is now a tidyverse autoload, I believe, via broom), geom_mosaic throws this error:

Error in alpha(data$fill, data$alpha) : 
  Data must either be a data frame or a matrix

Unloading psych dependencies and then unloading psych makes it work, because of the alpha function.

Specifying scales::alpha() in your code should fix this?

draw_panel = function(data, panel_scales, coord) {
 #  cat("draw_panel in GeomMosaic\n")
# browser()
   if (all(is.na(data$colour)))
     data$colour <- scales::alpha(data$fill, data$alpha) # regard alpha in colour determination

Thanks for the suggestion. The change has been made.
