Dear John and the rest,
Finally, it seems that now I have found a solution for the problem:
options(width=200) #make window size bigger
#create a test dataset (which is a correlation matrix)
#with row and col names
#extract from this matrix only those correlations
#that fulfill a specific criter

Perhaps he wants
which(w>0.6,arr.ind=TRUE)
It is
Hey Christoph,
It is not clear what do you want to "extract".
w[w>0.6] does give you the correlation values above 0.6. What is your
question?

w[w>.6] seems to work for me. I cut down the size of
the matrix for easier visual inspection.
m=matrix(sample(1:20,replace=T),4,5)
w=cor(m,use="pairwise.complete.obs")
w
w[w>.6]
perhaps perferabely
w[w>0.6 & w!=1]

If I understand what you want, you can use 'which'
which(w>0.6, arr.ind=T)

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
