nelder_calc: Calculate Nelder Fan design

In kevinwolz/sysdesign: An R Toolbox for Creating & Analyzing Systematic Experimental Designs in Biology

Description

Calculates Nelder Fan design. Used within nelder.

Usage

nelder_calc(
  alpha,
  theta,
  tau,
  D1,
  N,
  max.angle,
  n.spokes,
  arc.borders,
  spoke.borders
)

Arguments

alpha	Rate of change along the spokes.
theta	The angle between the spokes.
tau	The "rectangularity" proportion
D1	Plant density within the first experimental arc (plants ha-1) (i.e. upper extreme of experimental plant density range).
N	Number of experimental arcs (i.e. number of densities to be tested within D1 to DN).
max.angle	The maximum rotation (in degrees) of the design. If 360, then a full circle design will be created.
n.spokes	The number of spokes.
arc.borders	Number of border arcs on either extreme.
spoke.borders	Number of border spokes on either extreme (only used if max.angle < 360).

Value

A list containing the plant and plot data.
