error using lapply with oneway_test (coin package)

That's a scoping problem, I think a bug in oneway_test.  Because the formula 
var ~ group is created with the anonymous function within lapply, its 
environment should be the evaluation frame of that function call and var 
should be visible.  If I replace oneway_test() with lm() it works.

I think a workaround is to construct the data argument explicitly, i.e.

lapply(y, function(var) oneway_test(var ~ group, data.frame(var=var, 
group=group)))

I've cc'd Torsten Hothorn, the maintainer of coin.
