Examples

# load test data
data(sp2)

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

# assign abrupt textural change to a profile
newdata <- data.frame(id = c("hon-21"),
                      restrkind = "abrupt textural change",
                      restrdep = 46)

# do left join
restrictions(sp2) <- newdata

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