PST (version 0.94.1)

cplot: Plot single nodes of a probabilistic suffix tree

Description

Plot the next symbol probability distribution associated with a particular node in a PST

Usage

# S4 method for PSTf
cplot(object, context, state, main=NULL, all=FALSE, x.by=1, y.by=0.2, by.state=FALSE, ...)

Arguments

object

A probabilistic suffix tree, i.e., an object of class "PSTf" as returned by the pstree, prune or tune function.

context

character. Label of the node to plot, provided as a string where states are separated by '-', see examples.

state

logical. Under development.

main

character. Main title for the plot. By default, the title is the node label.

all

logical.

x.by

numeric. Interval for the ticks on the x axis (segments).

y.by

numeric. Interval for the ticks on the y axis (probability).

by.state

logical. If TRUE, the representation of the probability distribution is done separately for each state of the alphabet.

...

arguments to be passed to the plot function or other graphical parameters.

Details

The cplot() function displays a single node labelled with context of the tree where one or mode barplots (if object is a segmented PST) represent the probability distribution(s) stored in the node. For more details, see Gabadinho 2016.
