As far as I can see, maybe you should not use the redirect command in
this case and skip the 'data' argument then it should work:


else the results from 'aov(..)' are just redirected to aov.split.04 but
not passed to standard output for 'summary(...)'. And it probably does
not have a data argument?

Maybe someone else could explain why?
