Comment: C: How to get a half correlation matrix?
... I know what you mean. But you also mean that it is impossible to compute directly the upper or the lower triangle on my first matrix? I necessarily need to create another matrix to the dimensions of my first matrix (`res <- matrix(NA,ncol(data),ncol(data))`), and then compute the correlations an ...

How to get a half correlation matrix?
... Hi guys, I would like to know if it is possible to compute the half of a correlation matrix? I mean, I don't want to compute the whole matrix, and then extract just the upper or the lower half - I want to get directly the half matrix? I use R. I have already a code but it gives the whole matrix : ...
