### Arguments

`phylog` | an object of class phylog
`pfms` | a list of objects of class pfm
`circle` | a size coefficient for the outer circle of the labels. Please note this is the position of inner.label.cirle.
`circle.motif` | a size coefficient for the motif 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
`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
`draw.box` | if TRUE draws a box around the current plot with the function box()
`col.leaves` | a vector of colors for leaves labels
`col.leaves.bg` | a vector of colors for background of leaves labels
`col.leaves.bg.alpha` | alpha value [0, 1] for the colors of backgroud of leaves labels
`col.bg` | a vector of colors for tree background
`col.bg.alpha` | a alpha value [0, 1] of colors for tree background
`col.inner.label.circle` | a vector of colors for inner cirlce of pfms
`inner.label.circle.width` | width for inner circle of pfms
`col.outer.label.circle` | a vector of colors for outer circle of pfms
`outer.label.circle.width` | width for outer circle of pfms
`clockwise` | a logical value indicating if slices are drawn clockwise or counter clockwise
`init.angle` | number specifying the starting angle (in degrees) for the slices. Defaults to 0 (i.e., ‘3 o’clock') unless clockwise is true where init.angle defaults to 90 (degrees), (i.e., ‘12 o’clock')
`angle` | number specifying the angle (in degrees) for phylogenic tree. Defaults 360
`pfmNameSpliter` | spliter when name of pfms contain multiple node of labels.leaves
`rcpostfix` | the postfix for reverse complements
`motifScale` | the scale of logo size
`ic.scale` | logical. If TRUE, the height of each column is proportional to its information content. Otherwise, all columns have the same height.
`plotIndex` | logical. If TRUE, will plot index number in the motifLogo which can help user to describe the motifLogo
`IndexCol` | The color of the index number when plotIndex is TRUE.
`IndexCex` | The cex of the index number when plotIndex is TRUE.
`groupDistance` | show groupDistance on the draw
`groupDistanceLineCol` | groupDistance line color, default: red
`plotAxis` | logical. If TRUE, will plot distance axis.
`font` | font of logo
