restrictions<- | R Documentation |
Restrictions data in an object inheriting from data.frame
can easily be added via merge (LEFT JOIN). There must be one or more same-named profile ID columns on the left and right hand side to facilitate the join: restrictions(spc) <- newdata
.
## S4 replacement method for signature 'SoilProfileCollection'
restrictions(object) <- value

A SoilProfileCollection |

An object inheriting |
# 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)
