plot motif over another motif to emphesize the difference.

plotMotifOverMotif(
  motif,
  backgroundMotif,
  bgNoise = NA,
  font = "Helvetica-Bold",
  textgp = gpar()
)

Arguments

motif	an object of `pcm` or `pfm`
backgroundMotif	an object of `pcm` or `pfm`
bgNoise	if it is not NA, test will using a background by Dirichlet(1)-distributed random frequencies with weight bg.noise. The value of bgNoise should be a number in the range of 0 to 1, eg. 0.05

Examples


pcms <- readPCM(file.path(find.package("motifStack"), "extdata"),"pcm$")
len <- sapply(pcms, function(.ele) ncol(.ele$mat))
pcms <- pcms[len==7]
plotMotifOverMotif(pcms[[1]], pcms[[2]], bgNoise=0.05)
