LagBasis: Create and manipulate lag basis functions
In asw221/dlm: Distributed Lag Models for Built Environment Applications

S4 class object to store and query components of computed lag basis functions. User interface for creating this class can be found in basis.

See basis for details of the decomposition

x: radii that define ring-shaped areas around participant locations
x.center: the value x was centered to prior to computing the basis
x.scale: the value x was scaled by prior to computing the basis
C0: C_0 part of basis matrix
K1: K_1 part of basis matrix
dist.fun: the function applied to the elements of x to compute the basis
