SoilTextureLevels function

Ranking Systems for USDA Soil Texture Classes

Ranking Systems for USDA Soil Texture Classes

Generate a vector of USDA soil texture codes or class names, sorted according to approximate particle size

SoilTextureLevels(which = "codes", simplify = FALSE)

Arguments

  • which: 'codes' (texture codes) or 'names' (texture class names)
  • simplify: Return 12-class factor levels (TRUE) or 21-class factor levels (default: FALSE)? The 12-class system does not separate sands, loamy sands and sandy loams into sand fraction variants (e.g. "very fine sandy loam" in the 21-class system is "sandy loam" in 12-class system)

Returns

an ordered factor

Examples

# class codes SoilTextureLevels() # class names SoilTextureLevels(which = 'names') # simpler class names SoilTextureLevels(which = 'names', simplify = TRUE)
