PlotCharacter: Plot the distribution of a character on a tree

In TreeSearch: Phylogenetic Analysis with Discrete Character Data

Plot the distribution of a character on a tree

Description

Reconstructs the distribution of a character on a tree topology using the modified Fitch algorithm presented in \insertCiteBrazeau2019;textualTreeSearch.

Usage

PlotCharacter(
  tree,
  dataset,
  char = 1L,
  updateTips = FALSE,
  plot = TRUE,
  tokenCol = NULL,
  ambigCol = "grey",
  inappCol = "lightgrey",
  ambigLty = "dotted",
  inappLty = "dashed",
  plainLty = par("lty"),
  tipOffset = 1,
  unitEdge = FALSE,
  ...
)

Arguments

tree	A tree of class phylo.
dataset	A phylogenetic data matrix of phangorn class phyDat, whose names correspond to the labels of any accompanying tree.
char	Index of character to plot.
updateTips	Logical; if FALSE, tips will be labelled with their original state in dataset.
plot	Logical specifying whether to plot the output.
tokenCol	Palette specifying colours to associate with each token in turn, in the sequence listed in attr(dataset, "levels").
ambigCol, ambigLty, inappCol, inappLty, plainLty	Colours and line types to apply to ambiguous, inapplicable and applicable tokens. See the lty graphical parameter for details of line styles. Overrides tokenCol.
tipOffset	Numeric: how much to offset tips from their labels.
unitEdge	Logical: Should all edges be plotted with a unit length?
...	Further arguments to pass to plot.phylo().

Value

PlotCharacter() invisibly returns a matrix in which each row corresponds to a numbered tip or node of tree, and each column corresponds to a token; the tokens that might parsimoniously be present at each point on a tree are denoted with TRUE.

Examples

# Set up plotting area
oPar <- par(mar = rep(0, 4))

tree <- ape::read.tree(text = 
  "((((((a, b), c), d), e), f), (g, (h, (i, (j, (k, l))))));")
## A character with inapplicable data
dataset <- TreeTools::StringToPhyDat("23--1??--032", tips = tree)
plotted <- PlotCharacter(tree, dataset)
plotted

# Character from a real dataset 
data("Lobo", package = "TreeTools")
dataset <- Lobo.phy
tree <- TreeTools::NJTree(dataset)
PlotCharacter(tree, dataset, 14)
par(oPar)
