## plot sequence logo stacks with a ape4-style phylogenic tree

### Description

plot sequence logo stacks with a ape4-style phylogenic tree

### Usage

    plotMotifStackWithPhylog(
      phylog,
      pfms = NULL,
      f.phylog = 0.3,
      f.logo = NULL,
      cleaves = 1,
      cnodes = 0,
      labels.leaves = names(phylog$leaves),
      clabel.leaves = 1,
      labels.nodes = names(phylog$nodes),
      clabel.nodes = 0,
      font = "Helvetica-Bold",
      ic.scale = TRUE
    )

### Arguments

`phylog` | an object of class phylog
`pfms` | a list of objects of class pfm
`f.phylog` | a size coefficient for tree size (a parameter to draw the tree in proportion to leaves label)
`f.logo` | a size coefficient for the motif
`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")*clavel.leaves
`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
`font` | font of logo
`ic.scale` | logical If TRUE, the height of each column is proportional to its information content. Otherwise, all columns have the same height.

### Value

none
