geom_interpolate_tern: Ternary Interpolation

Description

This is the heavily requested geometry for interpolating between ternary values, results being rendered using contours on a ternary mesh.

Usage

geom_interpolate_tern(mapping = NULL, data = NULL,
  stat = "InterpolateTern", position = "identity", lineend = "butt",
  linejoin = "round", linemitre = 1, na.rm = FALSE,
  n = getOption("tern.mesh.size"), buffer = getOption("tern.mesh.buffer"),
  ...)

Arguments

mapping
The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data
A layer specific dataset - only needed if you want to override the plot defaults.
stat
The statistical transformation to use on the data for this layer.
position
The position adjustment to use for overlapping points on this layer
lineend
Line end style (round, butt, square)
linejoin
Line join style (round, mitre, bevel)
linemitre
Line mitre limit (number greater than 1)
na.rm
If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.
n
Number of grid points in each direction of the mesh. Can be scalar or a length-2 integer vector.
buffer
factor to buffer the mesh, to prevent ugly truncation of contours, 1.0 means no buffering
...
other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.

Aesthetics

[results=rd,stage=build]{ggtern:::rd_aesthetics("geom", "InterpolateTern")} data(Feldspar) ggtern(Feldspar,aes(x=Or,y=An,z=Ab)) + geom_interpolate_tern(aes(value=P.Gpa,color=..level..),binwidth=20) + geom_point() stat_interpolate_tern
