I presume that this is the function from package coda (not mentioned and 
we have no sessionInfo() and the 'replicable code' does not work).

And what disturbed you about this?  coda::crosscorr.plot ends


when I think it would better end invisible(), but that is something to 
raise with the maintainer (Cc:ed here), not the list.

return() does return NULL, visibly (as its help page says).

It needs 'library(lme4)' to be replicable!

which does give a credible plot.
