Transform a SPC with expressions based on site or horizon level attributes
Description
transform() is a function used for modifying columns in SoilProfileCollections.
It allows the user to specify an arbitrary number of expressions that resolve to the (re-)calculation of one or more site or horizon level attributes. For instance: mutate(spc, thickness = hzdepb - hzdept). The expressions may depend on one another, and are evaluated from left to right.
Usage
## S4 method for signature 'SoilProfileCollection'
transform(`_data`, ...)
Arguments
_data
A SoilProfileCollection
...
Comma-separated set of R expressions e.g. thickness = hzdepb - hzdept, hzdepm = hzdept + round(thk / 2)
Value
A SoilProfileCollection
