Plots four diagnostic plots for objects of class "lmf": a plot of residuals against fitted values, a Normal Q-Q plot, a Scale-Location plot of the square root of standardized residuals against fitted values and a plot of standardized residuals against leverage with indications of cooks distance.

`x` |
an object of class "lmf". |

`what` |
the part of the model for which diagnostic plots should be generated. Options are 'total' (default) for the overall plots and 'age-year' for plots for each separate linear regression for each age within each year. |

`...` |
additional arguments to be passed through to plotting functions. |

The function is constructed partly from modifications of script
from the `plot.lm`

function in package stats. See `?plot.lm`

for details on the plots provided.
