| pwm-class {seqLogo} | R Documentation |
An object of class "pwm" represents the 4xW position weight
matrix of a DNA sequence motif. The entry in row i, column j gives the
probability of observing nucleotide c("A","C","G","T")[i] in
position j of the motif.
Objects can be created by calls of the form new("pwm", ...).
pwm:"matrix" The position
weight matrix.width:"numeric" The width of the motif.alphabet:"character" The sequence
alphabet. Currently, only "DNA" is supported.
signature(object = "pwm",...) Prints the
position weight matrix. signature(x = "pwm",...) Prints the
position weight matrix.signature(object = "pwm") Prints the
position weight matrix. signature(x = "pwm") Plots the
sequence logo of the position weight matrix. Oliver Bembom, bembom@berkeley.edu
