Subset SPC based on result of performing function on each profile

Description

subApply() is a function used for subsetting SoilProfileCollections. It currently does NOT support for "tidy" lexical features in the ... arguments passed to profileApply(). The expectation is that the function .fun takes a single-profile SoilProfileCollection and returns a logical value of length one. The use case would be for any logical comparisons that cannot be evaluated inline by subSPC() because they require more than simple logical operations.

Usage

## S4 method for signature 'SoilProfileCollection'
subApply(object, .fun, ...)

Arguments

object	A SoilProfileCollection
.fun	A function that takes a single profile, returns logical of length 1.
...	Additional arguments are passed to .fun

Value

A SoilProfileCollection.
