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", ...)
.
