I do
Try this:

Hey Everyone,
Im fresh new in R, and Im supposed to write a code to give me a correlation
between two rankings. So I have two ranking lists, which contain file names,
e.g.:
Ranking list 1:

match() will return an NA, if it cannot find a match, in which case
you could use the argument: use="pairwise.complete.obs") in cor() to

Dear David,
Are the rankings the numbers? Like
List 1:
1
3
2
If so you should be able to do it fairly easily with cor() If you
have a lot of file names and need to extract the numbers look at
?strsplit or ?substring. This will be easier or harder depending how
variable the names are. For
9 matches
