## Plot a Functional Data Object

### Description

Functional data observations, or a derivative of them, are plotted. These may be either plotted simultaneously, as matplot does for multivariate data, or one by one with a mouse click to move from one plot to another. The function also accepts the other plot specification arguments that the regular plot does.

### Usage

plotFd(fd, Lfd=0, matplt=TRUE, href=TRUE, nx=101, xlab=xlabel, ylab=ylabel, xlim=rangex, ylim=rangey, ...)

### Arguments

`fd` |
A functional data object. |

`Lfd ` |
Either a nonnegative integer or a linear differential operator object. If present, the derivative or the value of applying the operator is plotted rather than the functions themselves. |

`matplt ` |
A logical variable. If TRUE, the observations are all plotted simultaneously. If not, they are plotted one by one, with a mouse click to move to the next plot. |

`href ` |
A logical variable. If TRUE, a horizontal dotted line is plotted at zero. |

`nx ` |
The number of points to use to define the plot. The default is usually enough, but for a highly variable function more may be required. |

`xlab ` |
A label for the abscissa. |

`ylab ` |
A label for the ordinate. |

`xlim ` |
Axis limits for the abscissa. |

`ylim ` |
Axis limits for the ordinate. |

`... ` |
Additional arguments that can be used in all plotting programs. |

### Details

### Value

A plot of the functional data. Note that for multivariate data, a suitable array must first be defined using the par function.
