what are exactly "some operations"? if you could provide a
reproducible code, it would make it easier to understand what you're
trying to achieve.
for example, if you were to get the means, you could do something like:
theMeans <- rapply(test, mean)

Thanks Henrique. I would have not thought of the syntax you suggest, though
it embodies the sort of multilevel (not quite recursive) application of
lapply I was thinking of. However, it returns ³test² with V2 missing,
everything else intact. Strange; I can't really state in words what I think
it
If I understand correctly your question, you can try something about like
this:
# Access all elements named 'V1' in your list
lapply(test, lapply, '[', 'V1')
