ggseqlogo: Quick sequence logo plot

In ggseqlogo: A 'ggplot2' Extension for Drawing Publication-Ready Sequence Logos

Quick sequence logo plot

Description

ggseqlogo is a shortcut for generating sequence logos. It adds the ggseqlogo theme theme_logo by default, and facets when multiple input data are provided. It serves as a convenient wrapper, so to customise logos beyond the defaults here, please use geom_logo.

Usage

ggseqlogo(
  data,
  facet = "wrap",
  scales = "free_x",
  ncol = NULL,
  nrow = NULL,
  ...
)

Arguments

data	Character vector of sequences or named list of sequences. All sequences must have same width
facet	Facet type, can be 'wrap' or 'grid'
scales	Facet scales, see facet_wrap
ncol	Number of columns, works only when facet='wrap', see facet_wrap
nrow	Number of rows, same as ncol
...	Additional arguments passed to geom_logo

Examples

# Load sample data
data(ggseqlogo_sample)

# Plot a single DNA sequence logo
p1 = ggseqlogo( seqs_dna[[1]] )
print(p1)

# Plot multiple sequence logos at once
p2 = ggseqlogo( seqs_dna )
print(p2)
