Plot diagnostics for an lmf object
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.

an object of class "lmf".
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
plot.lm function in package stats. See
for details on the plots provided.
