Dear Colleagues, I would like to only inspect rules that contain a certain label substring on the rhs. In this special case the item labels are built like this: <itemtype>_<itemvalue> e.g. "Artikelgruppe_E0815" what I want to do is only show rules where "Artikelgruppe" is contained in the rhs - has anybody an idea how this could work?

Then one options might be something like (untested): isets <- LIST(items(rhs(foo))) lapply(isets, function(x) grep("Artikelgruppe", isets)) oop, I just realized: do you mean RHS of the association rule or RHS of the <foo>_<bar>? hth, + seth
