. This vector
must have names that correspond to the tip labels in the
phylogenetic tree (tree$tip.label
). Unresolved clades are
not supported.nodes
(see
Details).sampling.f[i]
is the proportion of species in state i
that are present in
the phylogeny. A value of c(0.5, 0.75, 1)
means that half of
species in state 0, three quarters of species in state 1, and all
species in state 2 are included in the phylogeny. By default all
species are assumed to be known.states
vector is always checked to make sure
that the values are integers on 0:2
. If strict
is
TRUE
(the default), then the additional check is made that
every state is present. The likelihood models tend to be
poorly behaved where states are missing, but there are cases
(missing intermediate states for meristic characters) where allowing
such models may be useful.make.bisse
.split.t
argument. If this is Inf
, split at the base of the branch (as in
MEDUSA). If 0
, split at the top (closest to the present, as in
the new option for MEDUSA). If 0 < split.t < Inf
then we split
at that time on the tree (zero is the present, with time growing
backwards).The nodes
at the top of the split location are specified as a
vector of node names. For example, a value of c("nd10",
"nd12")
means that the splits are along the branches leading from each
of these nodes towards the root.
