Plot Summary object for interval search models

Description

Produces a plot for summary object of a fitted interval search model. Plot 'visited' points against iteration steps. start.N points are initial points selected before interval search starts.

Usage

## S3 method for class 'sum.intsearch'
plot(x, type = "summary", startN = 21, ...)

Arguments

x	an object of class sum.intsearch as returned by the function summary.intsearch.
type	type of plot to be drawn, type="summary" will plot the partial log likelihood deviance as a function of both tuning parameters \alpha and log \lambda. The final solution will be highlighted by solid red line. Alternativly, type="points" will draw the distribution of initial and visited points of the interval search plotted in chronological order.
startN	number of initial points. Needed if type="points"
...	additional argument(s)
