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 |

`ur` |
Upper right limits for the grid. By default, |

### Examples

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