Thanks Sarah. Silly mistake. I wrote the syntax when testing the
correlation matrix, hence the symmetric = TRUE statement. I then
thought, hang on a minute; I better check that and forgot to unwind
the condition.
At least I'm not going mad!

Hi,
How about because of this:

Your matrix isn't symmetric. If you claim that it is, R discards the
upper triangle without checking. You really want this:
