hzDepthTests: Tests of horizon depth logic

Description

Function used internally by checkHzDepthLogic(), glom() and various other functions that operate on horizon data from single soil profiles and require a priori depth logic checks. Checks for bottom depths less than top depth / bad top depth order ("depthLogic"), bottom depths equal to top depth ("sameDepth"), overlaps/gaps ("overlapOrGap") and missing depths ("missingDepth"). Use names(res)[res] on result res of hzDepthTest() to to determine type of logic error(s) found -- see examples below.

Usage

hzDepthTests(top, bottom = NULL)

Value

A named logical vector containing TRUE for each type of horizon logic error found in the given data.

Arguments

top

A numeric vector containing horizon top depths. Or a data.frame with two columns (first containing top depths, second containing bottom)

bottom

A numeric vector containing horizon bottom depths.

Examples

# no logic errors
res <- hzDepthTests(top = c(0,10,20,30), bottom = c(10,20,30,50))
names(res)[res]

# bottom < top
hzDepthTests(top = c(10,20,30,50), bottom = c(0,10,20,30))
names(res)[res]

# bottom == top
hzDepthTests(top = c(10,20,30,50), bottom = c(0,20,20,30))
names(res)[res]

# overlap
hzDepthTests(top = c(0,5,20,30), bottom = c(10,20,30,50))
names(res)[res]

# gap
hzDepthTests(top = c(0,15,20,30), bottom = c(10,20,30,50))
names(res)[res]

# missing
hzDepthTests(c(0,15,NA,30),c(10,NA,30,50))
names(res)[res]
