The structure of the lists should be the same. That is,
as a tree, the two lists should be isomorphic. For example,
special_or_lists(list(a = FALSE, b = list(b = TRUE, c = FALSE)),
list(a = FALSE, b = list(b = FALSE, c = TRUE)))
yields
list(a = FALSE, b = list(b = TRUE, c = TRUE))
and
special_or_lists(list(a = FALSE, b = list(b = TRUE, c = FALSE)),
list(a = list(b = FALSE, c = TRUE), b = FALSE))
yields
list(a = list(b = FALSE, c = TRUE), b = list(b = TRUE, c = FALSE))
1 | special_or_lists(list1, list2)
|
list1 |
a list. |
list2 |
a list. |
Note that lists get ORed based on *order*, not on key names (as this could
be ambiguous), so make sure the two lists have the same comparable key orders.
For example, special_or_lists(list(a = TRUE, b = FALSE), list(b = FALSE, a = TRUE))
would mistakenly return list(a = TRUE, b = TRUE)
.
the or'ed list.
