I've a vector of pairwise correlations in the order low-index element 
precedes the high-index element, say:

corr(1,2)=0.1, corr(1,3)=0.2, corr(2,3)=0.3, corr(3,4)=0.4

How can I construct the corresponding correlation matrix?

I tried using the "combn"-function in "combinat" package:


, but to no avail...

Thank you for your help,
