Extract correlations from a matrix
Dear R users,
suppose I have a matrix of observations for which I calculate all
pair-wise correlations:
m=matrix(sample(1:100,replace=T),10,10)
w=cor(m,use="pairwise.complete.obs")
How do I extract only those correlations that are >0.6?
w[w>0.6] #obviously doesn?t work,
and I can?t find a way around it.
I would very much appreciate any help!
Best wishes
Christoph
