isScalar

Check if the argument is scalar, i.e. a numeric vector of length 1.

internal

Numerical integration of continuously differentiable
functions f(x,y) over simple closed polygonal domains.
The following cubature methods are implemented:
product Gauss cubature (Sommariva and Vianello, 2007,
<doi:10.1007/s10543-007-0131-2>),
the simple two-dimensional midpoint rule
(wrapping 'spatstat.geom' functions), and
adaptive cubature for radially symmetric functions via line
integrate() along the polygon boundary (Meyer and Held, 2014,
<doi:10.1214/14-AOAS743>, Supplement B).
For simple integration along the axes, the 'cubature' package
is more appropriate.
