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.
# S3 method for sum.intsearch
plot(x, type = "summary", startN = 21, ...)an object of class sum.intsearch as returned by the function
summary.intsearch.
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.
number of initial points. Needed if type="points"
