dx.fibers.micro {fiberLD} | R Documentation |
Density functions of the fiber length based on microscopy data
Description
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
).
Usage
dx.fibers.micro(x, par, r, model="ggamma")
dy.fibers.micro(x, par, model="ggamma")
dw.fibers.micro(x, par, r, model="ggamma")
Arguments
x |
vector of fiber length |
par |
vector of parameters for fiber length distribution |
r |
radius of the increment core |
model |
either |
Value
returns a vector of density values

Examples
library(fiberLD)
r <- 2.5
par <- c(1.8,2.7,2.6)
x <- seq(.01, 2*r-.01,length=100)
f1 <- dy.fibers.micro(x, par)
plot(x,f1,type="l")
f2 <- dx.fibers.micro(x, par, r)
## getting the density in the tree that goes beyond the length
## of the diameter, 2r,...
w <- seq(0,8,length=200)
f3 <- dw.fibers.micro(w, par, r)
plot(w,f3,type="l")
