| sep.dbh {CTFS} | R Documentation |
sep.dbh creates a vector of the same length as the input
data file that contains the value for the DBH class of the tree.
This vector can be used with mortality,
growth, recruitment, and
abundance to compute rates and counts for each DBH
class. This function can also be used as a
template for writing other functions that use the function cut
which "bins" values into user defined bins (classes).
sep.dbh(census1, dbhclass = c(10, 100, 300))
census1 |
usually a tree data file which is a dataframe, but any object with a dim=NULL is also allowed |
dbhclass |
lower class boundaries for DBH classes, classes are nonoverlapping, no maximum dbh needed |
This function is usually used to create a vector of dbh classes for each
tree in a census file. However, it can also be used, usually within
another function, to generate a vector of dbh classes from a vector of
dbh values. This usage can make such code much more simple as the cut
function, labels and class limits are handled by sep.dbh.
sep.dbh returns a vector of values which have the
mode factor
