effective support for standard normal is [-supp,supp]
vector of binning grid sizes
vector of weights. Default is a vector of all ones.
not yet implemented
Returns a list with 2 fields
linear binning counts
vector (d=1) or list (d>=2) of grid points in each
As of ks 1.10.0, binning is available for unconstrained
(non-diagonal) bandwidth matrices. Code is used courtesy of A. &
J. Gramacki, and M.P. Wand. Default bgridsize are
d=1: 401; d=2: rep(151, 2); d=3: rep(51, 3); d=4: rep(21, 4).
