How to access values in s4 method
...s as follows:
require(IRanges);
query <- IRanges(c(1, 4, 9), c(5, 7, 10))
subject <- IRanges(c(2, 2, 10), c(2, 3, 12))
findOverlaps(query, subject)
Output of find overlap function is:
------------------
1> findOverlaps(query, tree)
An object of class "RangesMatching"
Slot "matchMatrix":
query subject
[1,] 1 1
[2,] 1 2

pairs
Hi, All,
I have an n by m matrix with each entry between 1 and 15000. I want to know
the frequency of each pair in 1:15000 that occur together in rows. So for
example, if the matrix is
2 5 1 6
1 7 8 2
3 7 6 2
9 8 5 7
Pair (2,6) (un-ordered) occurs together in rows 1 and 3. I want to return
the value 2 for this pair as well as that for all pairs. Is there a fast way
to do this avoiding loops?
