plot.phylog {ade4} | R Documentation

## Plot phylogenies

### Description

`plot.phylog` draws phylogenetic trees as linear dendograms.
`radial.phylog` draws phylogenetic trees as circular dendograms.
`enum.phylog` enumerate all the possible representations for a phylogeny.

### Usage

    plot.phylog(x, y = NULL, f.phylog = 0.5, cleaves = 1, cnodes = 0,
     labels.leaves = names(x$leaves), clabel.leaves = 1,
     labels.nodes = names(x$nodes), clabel.nodes = 0, sub = "",
     csub = 1.25, possub = "bottomleft", draw.box = FALSE, ...)
    radial.phylog(phylog, circle = 1, cleaves = 1, cnodes = 0,
     labels.leaves = names(phylog$leaves), clabel.leaves = 1,
     labels.nodes = names(phylog$nodes), clabel.nodes = 0,
     draw.box = FALSE)
    enum.phylog(phylog, no.over = 1000)

### Arguments

`x, phylog` | an object of class `phylog`
`y` | a vector which values correspond to leaves positions
`f.phylog` | a size coefficient for tree size (a parameter to draw the tree in proportion to leaves label)
`circle` | a size coefficient for the outer circle
`cleaves` | a character size for plotting the points that represent the leaves, used with `par("cex")*cleaves`. If zero, no points are drawn
`cnodes` | a character size for plotting the points that represent the nodes, used with `par("cex")*cnodes`. If zero, no points are drawn
`labels.leaves` | a vector of strings of characters for the leaves labels
`clabel.leaves` | a character size for the leaves labels, used with `par("cex")*clabel.leaves`. If zero, no leaves labels are drawn
`labels.nodes` | a vector of strings of characters for the nodes labels
`clabel.nodes` | a character size for the nodes labels, used with `par("cex")*clabel.nodes`. If zero, no nodes labels are drawn
`sub` | a string of characters to be inserted as legend
`csub` | a character size for the legend, used with `par("cex")*csub`
`possub` | a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")
`draw.box` | if TRUE draws a box around the current plot with the function `box()`
`...` | further arguments passed to or from other methods
`no.over` | a size coefficient for the number of representations

### Details

The vector y is an argument of the function `plot.phylog` that ensures to plot one of the possible representations of a phylogeny. The vector y is a permutation of the set of leaves {1,2,...,f} compatible with the phylogeny's topology.

### Value

The function `enum.phylog` returns a matrix with as many columns as leaves. Each row gives a permutation of the set of leaves {1,2,...,f} compatible with the phylogeny's topology.
