[R] Normal probability plot of effects

Can anybody help me on this, please:

I want to produce a normal probability plot of effects for an unreplicated
design with 4 factors. 2 of the factors have 2 levels and the other 2 have 4
levels. Is it possible to produce such a graph?
I want to use this graph to decide which interaction effects are negligible
to combine them as an estimate of error.
Thank you in advance.
