ggtern (version 1.0.1.3)

ifthenelse: Internal Function

Description

ifthenelse function takes input arguments x, a and b and returns a

get_tern_extremes determines the limiting ternary coordinates given input coordinates.

arrow_label_formatter is a function that formats the labels directly adjacent to the axes on a ternary plot.

calc_element_plot Calculate the element properties, by inheriting properties from its parents, and compares to whether the local plot overrides this value. Based largely off the calc_element as provided in ggplot2

find_global is a function that conducts a named search for the name object instance, within the env environment. If an instance doesn't exist within the env environment, a search is then conducted within the ggtern and ggplot2 namespaces (in that order).

trytransform is an internal function which attempts to make ternary transformation. If fails, the original data is returned

Internal Function

Internal Function

Check required aesthetics are present This is used by geoms and stats to give a more helpful error message when required aesthetics are missing.

Compute ranges and dimensions of each panel, using the coord.

Modified Geom Smooth Proto

Modified Stat Smooth Proto

Internal functions to get and set the last coordinate system. An internal command for ggtern.

set_last_coord set the last coordinate system.

Internal Function

Exported instance of the imported grid arrow function

Arguments

coordinates

ggtern coordinate system, inheriting "ternary" and "coord" classes.

verbose

logical indicating verbose reporting to console

expand

numeric value to

label

character label

suffix

chacater suffix behind each label

sep

the seperator between label and suffix

element

the element name to calculate

theme

the theme to inherit from

plot

the plot to check locally for theme element, NULL is ok.

...

not used

name

character name of object to search for

env

environment to search within as first priority

data

the dataset

coord

the coordinates

data

data.frame

df

data.frame

remove

boolean remove or make zero

coord

coordinates

character

vector of required aesthetics

character

vector of present aesthetics

name

of object for error message

new

the coordinate system to set

a

argument a

b

argument b

x

argument x

Value

• data.frame representing the T, L and R amounts (Columns) at each of the tips (extremes) of the ternary plot area (Rows)

  Instance of the named object (if it exists), or NULL (if it does not).

  transformed data

  data.frame

  data.frame

  coordinate system

format

proto object $ draw :function (., data, scales, coordinates, limitarea = F, ...) $ default_stat:function (.) $ objname : chr "smoothtern" $ default_aes :function (.) $ guide_geom :function (.) $ required_aes: chr [1:2] "x" "y" $ draw_legend :function (., data, params, ...) parent: proto object .. parent: proto object

Details

This is a modified version of the original source as provided in ggplot2, which has the same functionality, however, the modification is such that the function now additionally searches within the ggtern namespace prior to the ggplot2 namespace.

get_last_coord is a function that returns the last coordinate system used.
