Tests of horizon depth logic
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.
hzDepthTests(top, bottom = NULL)
top |
A numeric vector containing horizon top depths. Or a |
bottom |
A numeric vector containing horizon bottom depths. |
A named logical vector containing TRUE for each type of horizon logic error found in the given data.
