Generate Soil Depth Class Matrix

Generate a boolean matrix of soil depth classes, actual soil depth class, and estimate of soil depth from a SoilProfileCollection object. Soil depths are estimated using pattern matching applied to horizon designations, by estimateSoilDepth(). The default REGEX pattern (p = 'Cr|R|Cd') will match most "contacts" described using the USDA / Soil Taxonomy horizon designation conventions.

getSoilDepthClass(
  f,
  depth.classes = c(very.shallow = 25, shallow = 50, mod.deep = 100, deep = 150,
    very.deep = 10000),
  ...
)

Arguments

f

a SoilProfileCollection object

depth.classes

a named vector of classes and depth breaks

...

arguments passed to estimateSoilDepth

Value

a data.frame containing soil depth and depth class for each profile, see examples
