ggseqlogo is an R package for generating publication-ready sequence logos using ggplot2.

Getting started

First install ggseqlogo from github using the devtools package:

devtools::install_github("omarwagih/ggseqlogo")

Load up the package and sample data

# Load the required packages
require(ggplot2)
require(ggseqlogo)

# Some sample data
data(ggseqlogo_sample)

Then draw a sequence logo

# Plot DNA sequence logo for transcription factor - data from JASPAR
ggseqlogo( seqs_dna$MA0001.1 )

# Plot protein sequence logo for kinase target phosphosites
ggseqlogo( seqs_aa$AKT1 )

For more examples, and a list of features see the full tutorial here.
