[R-sig-Geo] Select.spatial in spplot?

[Julius Tesoro]

Can select.spatial() be used in an existing spplot? I have tried selecting points (eq) from a plot generated from sp. However, when I invoke select.spatial(eq). It generates only the points without the background containing the faults. I need the background to select which earthquakes coalesce on which fault. Is there an alternative?

eq.pts<-list("sp.points",eq, col="blue", lwd=0.5, pch = 4)
	
spplot(faults,"Dip", xlim = c(110000,120000),
		ylim = c(3760000,3890000),
		sp.layout=list(eq.pts), 
		col = heat.colors(3))

select.spatial(eq)
