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)
)vector of boundary topography codes to be converted
code values, adjust as needed
line types
vector of line types with same length as x
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.
