dx.fibers.micro | R Documentation |
Functions to get values of the density functions of the fiber length on three different scales based on microscopy data, being the uncut fibres in the core: the uncut fibres in the increment core (dx.fibers.micro
), as true fiber lengths of those fibres that at least partially appears in the increment core (dy.fibers.micro
) and as the true fiber lengths in the standing tree (dw.fibers.micro
).
dx.fibers.micro(x, par, r, model="ggamma") dy.fibers.micro(x, par, model="ggamma") dw.fibers.micro(x, par, r, model="ggamma")
x |
vector of fiber length |
par |
vector of parameters for fiber length distribution |
r |
radius of the increment core |
model |
either |
returns a vector of density values
