panel_scales is a local copy of the ggplot2 function that calculates the scales for each panel, patched for the ternary system.
calculate_stats is a local copy of the ggplot2 function that calculates various stats for each layer.
train_ranges is a local copy of the ggplot2 function that computes ranges and dimensions of each panel, using the coord,
and patched for the ternary system.
"%+%" is a local copy of the ggplot2 add operator, no change other than exporting from the ggtern namespace
add_ggplot is a local copy of the ggplot2 method that adds elements to an existing gg object.
validate_element is a local copy of the ggplot2 function which checks the validity of a given theme element
against the elements table. Since the .elements_tree is an internal function, which is not exported, and modifications could not be made,
a new (and equivalent) .element_tree is created within ggtern to handle the new theme elements created within this package.
opts is deprecated. See the theme function.
plot_theme is a local copy of the method that determines the net theme between a plot and the current global theme.
add_theme is a local copy of the ggplot2 function which modifies the current theme, by a proposed theme.
It is slightly modified to handle 'logical' values the same way it handles 'character' or 'numeric' values,
which do not inherit from 'element' objects.
"%+replace%" is a local copy of the ggplot2 replace operator, no different other than being exported from the ggtern namespace.
update_theme is a local copy of a ggplot2 function, which copies elements from the new theme into an old theme.
calc_element is a local copy of the ggplot2 function which determines the net element based on inheritances, given input theme.
combine_elements is a local copy of the ggplot2 function that combines two theme elements
check_required_aesthetics is a local copy of the ggplot2 function that checks
if the required aesthetics are present. This is used by geoms and stats to give a more helpful error message
when required aesthetics are missing.
