Match list elements to another list
match_list(x, y, ...)list objects to be compared
additional arguments are ignored.
integer
vector with the same length as x. The
integer values give the position in y of the first match.
This function takes two list objects, and matches
the first list elements to the second list.
Each list contains list elements, for example if x
is a list, then the element in position i is accessed
using x[[i]].
A match between x[[i]] and y[[j]] is defined as follows:
all elements in x[[i]] are contained in y[[j]]
all elements in y[[j]] are contained in x[[i]]
For this function, item order and item duplication is ignored.
This function uses logic in the form all(x[[i]] %in% y[[j]]),
so it will operate properly with input objects compatible
with that format. The function is intended to be used with
list that contains atomic vectors.
