Convert to Glycan Structure Vector

Convert an object to a glycan structure vector.

Usage

as_glycan_structure(x)

Arguments

x

An object to convert to a glycan structure vector. Can be an igraph object, a list of igraph objects, a character vector of IUPAC-condensed strings, or an existing glyrepr_structure object.

Value

A glyrepr_structure object.

Examples

#> Attaching package: ‘igraph’
#> The following objects are masked from ‘package:stats’:
