Draw a Symbol Nomenclature For Glycan (SNFG)

Usage

draw_cartoon(
  structure,
  show_linkage = TRUE,
  orient = c("H", "V"),
  highlight = NULL
)

structure: A glyrepr::glycan_structure() scalar, or a string of any glycan structure text nomenclatures supported by glyparse::auto_parse().
show_linkage: Show linkage annotation or not. Default is TRUE.
orient: The orientation of glycan structure. "H" for horizontal, "V" for vertical. Default is "H"
highlight: An integer vector specifying the node indices to highlight. This argument is applicable only when structure is a glyrepr::glycan_structure(). Note that for a glyrepr::glycan_structure(), the node indices correspond exactly to the monosaccharides in its printed IUPAC nomenclature. For example, given glyrepr::as_glycan_structure("Gal(b1-3)[GlcNAc(b1-6)]GalNAc(a1-"), setting highlight = c(1, 3) will highlight the "Gal" and "GalNAc" nodes.
