plot_fit_2: A contour plot of the cost function.

In admixturegraph: Admixture Graph Manipulation and Fitting

Description

A contour plot of the cost function with respect to two admix variables specified by the user.

Usage

plot_fit_2(object, X, Y, resolution = 10, show_fit = FALSE, sigma = 6,
  grayscale = FALSE, ...)

Arguments

object	The fitted object.
X	An admix variable name (remember quotation marks).
Y	An admix variable name (remember quotation marks).
resolution	How densely is the function evaluated.
show_fit	Should the function plot the number of statistics where the graph fits the data instead of the cost_function?
sigma	If show_fit is TRUE then each statistic is considered fitted if the difference between a prediction and the observation statistics is no more than D*σ/(2*Z). Notice that even when plotting the number of fitted statistics, we have no guarantee that the chosen variables maximize this number as the fitting function still optimizes cost_function.
grayscale	Should the figure be plotted in grayscale or in colour?
...	Additional parameters passed to the plotting function contour.

Value

The matrix of values computed and plotted.
