Generates a simple QSM summary. The summary includes basic tree metrics, such as DBH, total height, and also volume and surface area arranged by totals and branching order.
Usage
summarise_qsm(cylinder, radius, triangulation = NULL)
summarize_qsm(cylinder, radius, triangulation = NULL)Arguments
- cylinder
QSM cylinder data frame
- radius
Radius column name either quoted or unquoted.
- triangulation
Calculate optional QSM triangulation metrics created with
import_treeqsm(). Only supports TreeQSM. Defaults toNULL.
