geom_Xline: Fixed Value Lines

In leogama/ggtern: An Extension to 'ggplot2', for the Creation of Ternary Diagrams

Description

Plot fixed value lines, for the top, left and right axis, analagous to the geom_hline and geom_vline geometries in ggplot2

Usage

geom_Tline(mapping = NULL, data = NULL, ..., Tintercept,
  na.rm = FALSE, show.legend = NA)

Tline(mapping = NULL, data = NULL, ..., Tintercept, na.rm = FALSE,
  show.legend = NA)

tline(mapping = NULL, data = NULL, ..., Tintercept, na.rm = FALSE,
  show.legend = NA)

geom_Lline(mapping = NULL, data = NULL, ..., Lintercept,
  na.rm = FALSE, show.legend = NA)

Lline(mapping = NULL, data = NULL, ..., Lintercept, na.rm = FALSE,
  show.legend = NA)

lline(mapping = NULL, data = NULL, ..., Lintercept, na.rm = FALSE,
  show.legend = NA)

geom_Rline(mapping = NULL, data = NULL, ..., Rintercept,
  na.rm = FALSE, show.legend = NA)

Rline(mapping = NULL, data = NULL, ..., Rintercept, na.rm = FALSE,
  show.legend = NA)

rline(mapping = NULL, data = NULL, ..., Rintercept, na.rm = FALSE,
  show.legend = NA)

Arguments

mapping	Set of aesthetic mappings created by aes() or aes_().
data	The data to be displayed in this layer. There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot(). A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify() for which variables will be created. A function will be called with a single argument, the plot data. The return value must be a data.frame, and will be used as the layer data. A function can be created from a formula (e.g. ~ head(.x, 10)).
...	Other arguments passed on to layer(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3. They may also be parameters to the paired geom/stat.
Tintercept, Lintercept, Rintercept	the intercepts for the T, L and R axis respectively
na.rm	If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.
show.legend	logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes. It can also be a named logical vector to finely select the aesthetics to display.
