[R] Pointwise Mutual Information

[pl.rudy at gmail.com]

Hi,

I want to calculate pointwise mutual information between "label" 2-gram, and
words in my corpus "1-gram". Any suggestions  as to how to go about it?

l =label 
w  = word 
C = reference collection

I want to calculate following:

p(w,l| C)
p(w| C)
p(l | C)
