Thanks for the report. This turns out to be a bug in the calculation of 
'skip', caused by my using the wrong variable name (this was introduced 
fairly recently when the behaviour of skip changed for multipage 
displays). Anyway, I'll post an updated version, meanwhile, a 
workaround is to specify skip explicitly, e.g., 

plot(dip,inner=~condition,layout=c(2,2), skip = rep(FALSE, 76))
