Description

Simple tests for horizon logic, based on a simple data.frame of ordered horizons.

Usage

test_hz_logic(i, topcol, bottomcol, test.NA = TRUE, strict = FALSE)

Arguments

i

a data.frame associated with a single soil profile, ordered by depth

topcol

character, giving the name of the column in i that describes horizon top depth

bottomcol

character, giving the name of the column in i that describes horizon bottom depth

test.NA

logicial, should tests for missing (NA) horizon top OR bottom boundaries be performed?

strict

logical, should continuity tests be performed-- i.e. for non-contiguous horizon boundaries

Value

• logical: TRUE --> pass, FALSE --> fail
