Hillslope position probability estimates from the SDA query service (SSURGO)
hillslopeProbability(s, replaceNA=TRUE) surfaceShapeProbability(s, replaceNA=TRUE) geomPosHillProbability(s, replaceNA=TRUE) geomPosMountainProbability(s, replaceNA=TRUE)
a character vector of soil series names, automatically normalized to upper case
boolean: should missing classes be converted to probabilities of 0?
data.frame object with rows representing soil series, and columns representing probability estimates of that series occurring at specified geomorphic positions or associated with a surface shape.
Probability values are computed from SSURGO data.
