basal_i

basal2dbh

The area of a circle of diameter <code>dbh</code>.

Computation of dendrometric and structural
parameters from forest inventory data. The objective is to provide an
user-friendly R package for researchers, ecologists, foresters,
statisticians, loggers and others persons who deal with forest inventory
data. Useful conversion of angle value from degree to radian, conversion from
angle to slope (in percentage) and their reciprocals as well as principal
angle determination are also included. Position and dispersion parameters
usually found in forest studies are implemented. The package contains
Fibonacci series, its extensions and the Golden Number computation.
