[R] mcmcsamp and variance ratios

Hi folks,
I have assumed that ratios of variance components (Fst and Qst in population genetics) could be estimated using the output of mcmcsamp
(the series on mcmc sample estimates of variance components).

What I have started to do is to use the matrix output that included the log(variances), exponentiate, calculate the relevant ratio, and apply either quantile or or HPDinterval to get confidence intervals.

This seems too simple but I can't think of what is wrong with it.

All thoughts appreciated.
