Add Data to Diagnostic Features Slot
Description
Diagnostic feature 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
## S4 replacement method for signature 'SoilProfileCollection'
diagnostic_hz(object) <- value
Arguments
object |
A SoilProfileCollection |
value |
An object inheriting |
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)
