[R] is there a way to recursilvely lapply

for a simple example:

x <- list()
x[["a"]] <- list(a=c(1,2,3),b=c(3,4,5))
x[["b"]] <- list(a=c(6,7,8),b=c(9,10,11))


this fails w/
Error in FUN(X[[1L]], ...) : invalid 'type' (list) of argument

Just wondering if I have overlooked something obvious.

one can also do:


but that assumes that you already know how many levels you have, and
that all the levels are consistent.
