plotTopMotifsSequence,MotifEnrichmentResults-method: Plot the top N enrichment motifs in a single sequence

Description

Plot the top N enrichment motifs in a single sequence

Arguments

obj

a MotifEnrichmentResults object

seq.id

either the sequence number or sequence name

n

the number of top ranked motifs to plot

bg

if to use background corrected P-values to do the ranking (if available)

id

if to show PWM IDs instead of target TF names

...

other parameters passed to plotMultipleMotifs()

Examples

if(require("PWMEnrich.Dmelanogaster.background")){
   ###
   # load the pre-compiled lognormal background
   data(PWMLogn.dm3.MotifDb.Dmel)

   # scan two sequences for motif enrichment
   sequences = list(DNAString("GAAGTATCAAGTGACCAGTAAGTCCCAGATGA"), DNAString("AGGTAGATAGAACAGTAGGCAATGAAGCCGATG"))

   res = motifEnrichment(sequences, PWMLogn.dm3.MotifDb.Dmel)

   # plot the top 4 motifs in a 2x2 grid
   plotTopMotifsSequence(res, 1, 4)

   # plot top 3 motifs in a single row
   plotTopMotifsSequence(res, 1, 3, row=1, cols=3)
