TernaryField: Draw a field on an existing ternary plot

In plot3logit: Ternary Plots for Trinomial Regression Models

Draw a field on an existing ternary plot

Description

TernaryField() adds the vector field returned by field3logit() to an existing ternary plot generated by Ternary::TernaryPlot().

Usage

TernaryField(
  field,
  ...,
  length = 0.05,
  conf = FALSE,
  npoints = 100,
  conf.args = list()
)

Arguments

field	object of class field3logit as returned by field3logit().
...	other arguments passed to or from other methods.
length	length of the edges of the arrow head (in inches).
conf	if FALSE confidence regions are not drawn, even if available; if TRUE confidence regions are drawn only if available; if a numeric value is passed, confidence regions at the specified confidence level are computed (if not already available) and drawn.
npoints	number of points of the border to be computed for each confidence region.
conf.args	graphical parameters of confidence regions to be passed to Ternary::TernaryPolygon().

Value

An object of class field3logit with confidence regions included, if computed within TernaryField().

mod0 <- nnet::multinom(employment_sit ~ gender + finalgrade, data = cross_1year)
field0 <- field3logit(mod0, 'genderFemale')
