Plot of predicted response vs observed or variable Values.

plotPrediction(object, ..., variable = NULL, smooth = FALSE,
  abline = TRUE, split = "none")

Arguments

object

An object of class modelAudit or modelResiduals.

...

Other modelAudit or modelResiduals objects to be plotted together.

variable

Only for modelAudit objects. Name of model variable to order residuals. If value is NULL data order is taken. If value is "Observed response" the data is ordered by a vector of actual response (y parameter passed to the audit function).

smooth

Logical, indicates whenever smooth line should be added.

abline

Logical, indicates whenever function y=x shoulbe added.

split

Character. If "model" plot will be splitted by model.
