draw_motif: Add protein motifs sites to ggplot2 object.

In brennanpincardiff/drawProteins: Package to Draw Protein Schematics from Uniprot API output

Add protein motifs sites to ggplot2 object.

Description

draw_motif adds protein motifs from Uniprot to ggplot2 object created by draw_canvas and draw_chains. It uses the data object. The ggplot2 function geom_rect is used to draw each of the motifs proportional to their number of amino acids (length).

Usage

draw_motif(p, data = data, alpha = 1.0, show.legend = TRUE)

Arguments

p	ggplot2 object ideally created with draw_canvas.
data	Dataframe of one or more rows with the following column names: 'type', 'description', 'begin', 'end', 'length', 'accession', 'entryName', 'taxid', 'order'. Must contain a minimum of one "CHAIN" as data$type.
alpha	Transparency of the rectangles representing the motifs.
show.legend	Option to include legend in this layer

Value

A ggplot2 object either in the plot window or as an object with an additional geom_rect layer.

Examples

# combines with draw_chains to plot chains and motifs
data("five_rel_data")
p <- draw_canvas(five_rel_data)
p <- draw_chains(p, five_rel_data, label_size = 1.25)
draw_motif(p, five_rel_data)
