This function will convert USDA-NCSS horizon boundary topography codes into line types, based on the Field Book for Describing and Sampling Soils, version 3.0.

hzTopographyCodeToLineType(
  x,
  codes = c("S", "W", "I", "B"),
  lty = c(1, 2, 3, 4)
)

Arguments

x

vector of boundary topography codes to be converted

codes

code values, adjust as needed

lty

line types

Value

vector of line types with same length as x

Details

Visualization of horizon boundary topography can be difficult, line type offers an additional visual cue. See hzTopographyCodeToOffset for an offset-based approach. Additional examples are available in the Visualization of Horizon Boundaries tutorial.
