silv_tree_dclass: Classify diameters in classes

In silviculture: Utility Functions for Forest Inventory and Silviculture

Classify diameters in classes

Description

Classifies the measured diameters into classes of a specified length

Usage

silv_tree_dclass(
  diameter,
  dmin = 7.5,
  dmax = NULL,
  class_length = 5,
  include_lowest = TRUE,
  return_intervals = FALSE
)

Arguments

diameter	A numeric vector of diameters
dmin	The minimum inventory diameter in centimeters
dmax	The maximum inventory diameter in centimeters. Values that are greater than dmax are included in the greatest class
class_length	The length of the class in centimeters
include_lowest	Logical. If TRUE (the default), the intervals are ⁠[dim1, dim2)⁠. If FALSE, the intervals are ⁠(dim1, dim2]⁠ [dim1, dim2)⁠. If FALSE, the intervals are ⁠(dim1, dim2]: R:dim1,%20dim2)%60.%20If%20FALSE,%20the%20intervals%20are%20%60(dim1,%20dim2
return_intervals	If FALSE, it returns the intervals. Otherwise (the default), it returns the class center

Value

A numeric vector

Examples

library(dplyr)
inventory_samples |>
  mutate(dclass = silv_tree_dclass(diameter))
