Allometric modeling
Description
Parameters in simple allometric model are evaluated on tree radial increments to compute diameters, basal areas, tree biomasses, etc.
Usage
1 
Arguments
cs 

mp 

un 
NULL, or bidimensional 
Details
The simple allometric model has the form: a * cs ^ b, with a,b being constants in mp
, and cs being scaledcummulative sums. Different dendrometric variables can be computed; for example, c(1,1)
produces diameters, and c(0.25 * pi,2)
computes basal areas. Argument mp
can have more than two parameters: c(a1,b1,a2,b2, ..., an,bn)
, with n
being the number of times that allometric model will be recursively implemented. Such recursive evaluation is useful to derive variables which depend on other allometric covariables: i.e allometric model would be implemented twice to recursively compute diameters and tree biomasses. A column of increments of cs (x) is also computed by implementing setdiff
.
Value
data.frame
object.
