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.
