make.soapgrid

list with elements <code>x</code> and <code>y</code> which give the locations
of the boundary vertices. The first and last elements should be the
same.

either one number giving the number of points along the 
<code>x</code> and <code>y</code> axes that should be used to create the grid, or
a vector giving the number in the <code>x</code> direction, then <code>y</code>
direction.

n.grid

This routine simply creates a grid of knots (in the correct format) to be
used as in the "internal" part of the soap film smoother

Density surface modelling of line transect data. A Generalized
Additive Model-based approach is used to calculate spatially-explicit estimates
of animal abundance from distance sampling (also presence/absence and strip
transect) data. Several utility functions are provided for model checking,
plotting and variance estimation.
