This function determines the type of monosaccharides in character vectors, glycan compositions, or glycan structures. Supported types: "concrete" and "generic" (see details below).

Usage

get_mono_type(x)

# S3 method for class 'character'
get_mono_type(x)

# S3 method for class 'glyrepr_structure'
get_mono_type(x)

# S3 method for class 'glyrepr_composition'
get_mono_type(x)

Arguments

x

Either of these objects:

  • A character vector of monosaccharide names;

  • A glycan composition vector ("glyrepr_composition" object);

  • A glycan structure vector ("glyrepr_structure" object).

Value

A character vector specifying the monosaccharide type(s). For structures and compositions, returns the type for each element.

Two types of monosaccharides

There are two types of monosaccharides:

  • concrete: e.g. "Gal", "GlcNAc", "Glc", "Fuc", etc.

  • generic: e.g. "Hex", "HexNAc", "HexA", "HexN", etc.

For the full list of monosaccharides, use available_monosaccharides().

Examples

# Character vector
get_mono_type(c("Gal", "Hex"))
#> [1] "concrete" "generic" 

# Glycan structures
get_mono_type(n_glycan_core(mono_type = "concrete"))
#> [1] "concrete"
get_mono_type(n_glycan_core(mono_type = "generic"))
#> [1] "generic"

# Glycan compositions
comp <- glycan_composition(c(Glc = 2, GalNAc = 1))
get_mono_type(comp)
#> [1] "concrete"
