Add data to the diagnostic slot
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

A SoilProfileCollection |
value |
An object inheriting |
# 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)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
