splitLogicErrors

Split a SoilProfileCollection into a list based on types of horizon logic errors

Description

Uses checkHzDepthLogic to identify presence of depth logic errors, same depths, missing depths, and overlaps/gaps between the horizons of each profile in a SoilProfileCollection.

Usage

splitLogicErrors(object, interact = FALSE, ...)

Arguments

`object`	A SoilProfileCollection
`interact`	Calculate interaction between the four logic errors for groups? Default: `FALSE` always returns 4 groups, one for each logic error type.
`...`	Additional arguments to `split.default`, called when `interact = TRUE`

Value

A named list of SoilProfileCollections (or NULL), with names: "depthLogic", "sameDepth", "missingDepth", "overlapOrGap". If interact = TRUE then the list elements groups determined by interaction() of the error types.

Examples

data(sp4)
depths(sp4) <- id ~ top + bottom

# no errors (all four list elements return NULL)
splitLogicErrors(sp4)

# NA in top depth triggers depth logic and missing depth errors
data(sp4)
sp4$top[1] <- NA
depths(sp4) <- id ~ top + bottom

splitLogicErrors(sp4)

# interact = TRUE gets errors for profile 1 in same group
#  and allows you to pass extra arguments to split.default()
splitLogicErrors(sp4, interact = TRUE, sep = "_", drop = TRUE)
