Extract and/or plot the model residuals

1 2	plot_residuals(x, gaps = FALSE, type = "deviance", band=c(-3,3), date.format = "%d/%m/%Y", new = TRUE, ...)

`x`	a model fitted by `fit_core` or a vector of the class `residuals`
`gaps`	a logical indicating whether `.ares.selection` should be honoured
`type`	a quoted string indicating the type of residuals to extract. Default is `"deviance"`. See `get_residuals`
`band`	a vector limits to plot the band. If `NULL`, the band is omitted. Default is `c(-3,3)`
`date.format`	a string indicating the date format for the horizontal axis. Default is `dd/mm/yyyy` See `strptime` for more options
`new`	if `TRUE` a new graph window is opened
`...`	further options for `plot`

If x is a model then the residuals are extracted with get_residuals. If x is a vector of the class residuals the function works as a method for the generic function plot, therefore only the graph is plotted.

A vector of class residuals with extracted and/or adjusted residuals of the model.
