Returns the fitted values of the model, either as computed in the model, or back to the original series level.

object 
An object of class ‘nlVar’; generated by

level 
How to return the fitted values. See below. 
... 
Currently not used. 
In case of a VAR in differences, in ADF specification, or a VECM, the fitted
values are actually in differences. With the option level="original"
,
the function returns the series in the original level.
For VAR in levels, the two arguments are evidently the same and hence it is not taken into account, returning a warning.
A matrix.
