initStand: Initialize the model Stand

In DGVM3D: 3D Forest Simulation Visualization Tool

Description

Initialize the model Stand

Usage

initStand(npatch = 1, year = 2000, soil = c(0, -0.5, -1.5), z = 0,
  layout = "square", composition = "spatial", dist = 0.05)

Arguments

npatch	number of patches
year	the initialization year
soil	a vector or matrix of soil depths.
z	the height of each patch.
layout	patch layout ('square' or 'linear'), a two element vector with number of rows/colums. A matrix for layout (not yet ready).
composition	'spatial' or 'temporal'
dist	the fractional distance between the hexagons

Details

If soil is a matrix, the number of columns must be equal to npatch. In that way each patch can have its own soil depth. The patches represented as hexagons can either be arranged in a square or in a line. The later one for example to represent a time series (succession).

Value

a Stand-class

Examples

## Not run: 
stand <- initStand(npatch=9, z=sort(rnorm(9, sd=2)))
stand3D(stand)

stand <- initStand(npatch=9, z=sort(rnorm(9, sd=2)), layout='linear')
stand3D(stand)

## End(Not run)
