plot.OUwie.contour function

Contour plot

Contour plot

A plotting function for visualizing likelihood surface for a pair of parameters using OUwie.contour data.

## S3 method for class 'OUwie.contour'
plot(x, mle.point=NULL, levels=c(0:20*0.1), xlab=NULL, 
ylab=NULL, xlim=NULL, ylim=NULL, col=grey.colors(21, start=0, end=1), ...)

Arguments

  • x: a OUwie.contour object.
  • mle.point: specifies the color for the maximum likelihood set of parameters. By default the point is not plotted (i.e., set to NULL.
  • levels: the levels at which to draw contour lines, measured as lnL units away from the best values.
  • xlab: allows users to specify the x-axis label.
  • ylab: allows users to specify the y-axis label.
  • xlim: allows users to specify the lower and upper limits of the x-axis.
  • ylim: allows users to specify the lower and upper limits of the y-axis.
  • col: indicates the color gradient.
  • ...: additional parameters to control the plot.
