plot.locfit {locfit} | R Documentation |

## Plot an object of class locfit.

### Description

The `plot.locfit`

function generates grids of ploting points, followed
by a call to `preplot.locfit`

. The returned object is then
passed to `plot.locfit.1d`

, `plot.locfit.2d`

or
`plot.locfit.3d`

as appropriate.

### Usage

```
## S3 method for class 'locfit'
plot(x, xlim, pv, tv, m, mtv=6, band="none", tr=NULL,
what = "coef", get.data=FALSE, f3d=(d == 2) && (length(tv) > 0), ...)
```

### Arguments

`x` |
locfit object. |

`xlim` |
Plotting limits. Eg. |

`pv` |
Panel variables, to be varied within each panel of a plot. May be specified as a character vector, or variable numbers. There must be one or two panel variables; default is all variables in one or two dimensions; Variable 1 in three or more dimensions. May by specified using either variable numbers or names. |

`tv` |
Trellis variables, to be varied from panel to panel of the plot. |

`m` |
Controls the plot resolution (within panels, for trellis displays). Default is 100 points in one dimension; 40 points (per dimension) in two or more dimensions. |

`mtv` |
Number of points for trellis variables; default 6. |

`band` |
Type of confidence bands to add to the plot. Default is |

`tr` |
Transformation function to use for plotting. Default is the inverse link function, or the identity function if derivatives are requested. |

`what` |
What to plot. See |

`get.data` |
If |

`f3d` |
Force the |
