Methods for function `plot`

to produce different diagonostic plots for an object of class "MultiChainLadder".

### Usage

1 2 3 4 5 6 7 |

### Arguments

`x` |
An object of class "MultiChainLadder". |

`y` |
"missing" |

`which.plot` |
This specifies which type of plot is desired. Its range is 1:5, but defaults to 1:4. "1" is the barplot of observed losses and predicted IBNR stacked and MSE predictions as error bars; "2" is a trajectory plot of the development pattern; "3" is the residual plot of standardized residuals against the fitted values; "4" is the Normal-QQ plot of the standardized residuals. "5" is the "xyplot" of development with confidence intervals for each accident year. Note that "3" and "4" are not available for portfolio. |

`which.triangle` |
This specifies which triangles are to be plotted. Default value is NULL, where all triangles plus the portfolio result will be plotted. |

`main` |
It should be a list of titles for each plot. If not supplied, use default titles. |

`portfolio` |
It specifies which triangles are to be summed as the portfolio, to be passed on to |

`lowess` |
