%description
An (upper) level set of a function is the set of inputs for which the
function value is at or above a specified threshold.  (Also called an
excursion set).  Applications of level sets include confidence or credible
regions for parameters of statistical models, where the function is the
likelihood or posterior density; regions where classification rules assign
high probability to a given class; and scientific or engineering models
where one is interested in input regions for which model output is above a
threshold.  This package maps out the boundary of a level set by finding
its intersections with collections of 1-dimensional rays, generalizing a
proposal by Kim and Lindsay (Statistica Sinica 21:923-948, 2011).  Tools
are provided to generate rays, find intersections, and visualize results.
The package makes few assumptions about the studied function: it may be
discontinuous, it may have a complicated feasible region, and the target
level set may be non-convex or have multiple, disconnected parts.
Vignettes describe package usage and show examples with two to five input
space dimensions.
