## Methods for Function plot

### Description

Methods for function `plot`

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

### Usage

```
## S4 method for signature 'MultiChainLadder,missing'
plot(x, y, which.plot=1:4,
which.triangle=NULL,
main=NULL,
portfolio=NULL,
lowess=TRUE,
legend.cex=0.75,...)
```

### 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` |
Logical. If |

`legend.cex` |
plotting parameter to be passes on to |

`...` |
optional graphical arguments. |

fit.liab <- MultiChainLadder(liab)
# generate diagonostic plots
par(mfcol=(c(3,2)))
plot(fit.liab,which.plot=1:2)
par(mfrow=(c(2,2)))
plot(fit.liab,which.plot=3:4)
plot(fit.liab,which.triangle=1,which.plot=5)
graphics.off()
## End(Not run)
