Description Usage Arguments Details Value Author(s) See Also Examples

This function returns a diagnostic plot to investigate the influence of a given ERP data frame on the grandaverage of a series of ERP data frames. A GUI is provided to explore the effect of removing a data frame (that is expected to be associated with a Subject) on the grandaverage. Two plots are superposed: the original grandaverage and the average removing the subject selected via the GUI.

	erp.infl(base, numbers, electrode, erplist=NULL,  startmsec=NULL, 
	endmsec=NULL, smo=NULL, outnumber=1, lwd=1, lty=1,  ...)

`base`	a string indicating the beginning of the name of the `data.frame` containing the ERP data.
`numbers`	the numbers of the subjects to be averaged by the function.
`electrode`	the electrode to be plotted.
`erplist`	a list containing the ERP data frames specified in `base` and `numbers`.
`startmsec`	the start time (in ms) of the ERP vector.
`endmsec`	the end time (in ms) of the ERP vector.
`smo`	the smoothing parameter to apply (see `smooth.spline`). Default is `NULL` and no smoothing is applied.
`outnumber`	The number of the subject that will be initially removed from the averaged (this value could be changed also via the GUI).
`lwd`	line width.
`lty`	line type.
`...`	further parameters to be passed to `erp` function called within `erp.infl`.

The function requires the package rpanel

The function returns a plot of a single electrode showing the influence of a subject on the grandaverage.
