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
