glydraw_style: Create a glycan drawing style

In glydraw: Draw Beautiful Symbol Nomenclature for Glycans

Create a glycan drawing style

Description

glydraw_style() collects the rendering options shared by glydraw's standalone drawings, grobs, ggplot2 layers, guides, and glycan scales. Supply the result with ⁠style =⁠ to reuse a visual specification. Explicit rendering arguments supplied to a drawing function override the style.

Usage

glydraw_style(
  show_linkage = TRUE,
  orient = c("H", "V"),
  fuc_orient = c("flex", "up"),
  red_end = "",
  edge_linewidth = 0.8,
  node_linewidth = 0.8,
  node_size = 1,
  colors = NULL
)

Arguments

show_linkage	Whether to show glycosidic linkage annotations.
orient	Glycan drawing orientation: "H" for horizontal or "V" for vertical.
fuc_orient	Fuc-like triangle orientation: "flex" or "up".
red_end	Reducing-end annotation. Use "~" for a wave.
edge_linewidth	Linewidth of glycosidic linkages.
node_linewidth	Linewidth of node borders.
node_size	Multiplier for the default node size.
colors	Optional named character vector of monosaccharide fill-color overrides.

Value

A glydraw_style object.

Examples

vertical_style <- glydraw_style(orient = "V", show_linkage = FALSE)
draw_cartoon("Gal(b1-3)GalNAc(a1-", style = vertical_style)
