lfgrid

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.

Examples

data(ethanol, package="locfit")
plot.eval(locfit(NOx ~ lp(E, C, scale=TRUE), data=ethanol, ev=lfgrid()))
