list.intersection.p: p-value for intersection of two gene lists.
Description
Calculates a p-value for observing a number of probe sets common to two lists drawn
from the same chip.Usage
list.intersection.p(N = 14000, N1 = 100, N2 = 200, common = 30)
Arguments
N
The selectable number of probe sets
N1
the number of probe sets on the first list.
N2
the number of probe sets on the second list
common
the number of probe sets in common to the two lists.
Value
- the p-value giving the probability of observing by chance at least as many in common as was actually observed.
