This function maps or "paints" an arbitrary, i.e., user-specified, discrete character history on the tree. paintSubTree paints the clade downstream of node with a particular state; whereas paintBranches paints only a specified branch.
paintSubTree(tree, node, state, anc.state="1", stem=FALSE)
paintBranches(tree, edge, state, anc.state="1")a phylogenetic tree as an object of class "phylo" or a modified object with mapped character traits.
an integer specifying the node number tipward of which the function should paint the derived state.
an integer or vector of integers specifying the node or tip numbers of the edges that should be painted in paintBranches.
a string (or numeric value) specifying the state to paint on the tree tipward of node.
the ancestral state to use; will only be applied if there are presently no character values mapped on the tree.
logical or numeric value indicating whether to use the derived state on the stem leading to node (or not, if stem=FALSE), or, alternatively, what fraction of the stem should be assigned to the derived clade. Note that for tip clades stem=FALSE is not allowed.
An object of class "simmap" that contains the specified paintings as a mapped discrete character.
