diagnostic_hz<-: Add data to the diagnostic slot

Description

Diagnostic data in an object inheriting from data.frame can easily be added via merge (LEFT JOIN). There must be one or more same-named columns containing profile ID on the left and right hand side to facilitate the join: diagnostic_hz(spc) <- newdata

Usage

diagnostic_hz(object) <- value

Arguments

object

A SoilProfileCollection

value

An object inheriting data.frame

Examples

# load test data
data(sp2)

# promote to SPC
depths(sp2) <- id ~ top + bottom

# assign two profiles a zone related to the mollic epipedon
newdata <- data.frame(id = c("hon-1","hon-17"),
                      featkind = "fixed-depth surface sample",
                      featdept = 0,
                      featdepb = 18)

# do left join
diagnostic_hz(sp2) <- newdata

# inspect site table: newvalue TRUE only for horizons
#  with top depth equal to zero
diagnostic_hz(sp2)
