Subset SPC based on result of performing function on each profile
Source:R/SoilProfileCollection-methods.R
subApply.RdsubApply() 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.
