Examples

data( centrarchidae )
## Run multiple MCMC chains.
handle.list <- lapply(1:4, function(x) ratematrixMCMC(data=centrarchidae$data
                      , phy=centrarchidae$phy.map, gen=10000, dir=tempdir()) )
## Read all to a list
posterior.list <- lapply(handle.list, readMCMC)
## Merge all posteriors in the list.
merged.four <- mergePosterior(posterior.list)
## Merge some of the posteriors.
merged.two <- mergePosterior(posterior.list[[1]], posterior.list[[3]])
