lfgrid {locfit} | R Documentation |
Locfit - grid evaluation structure.
Description
lfgrid()
is used to specify evaluation on a grid of points
for locfit.raw()
. The structure computes
a bounding box for the data, and divides that into a grid with
specified margins.
Usage
lfgrid(mg=10, ll, ur)
Arguments
mg |
Number of grid points along each margin. Can be a single number (which
is applied in each dimension), or a vector specifying a value for
each dimension.
|
ll |
Lower left limits for the grid. Length should be the number
of dimensions of the data provided to locfit.raw() .
|
ur |
Upper right limits for the grid. By default, ll and
ur are generated as the bounding box for the data.
