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

Description

Creates conformity-optimized Goelz Triangle experimental designs

Usage

goelz_optim(
  data,
  save.path = ".",
  MU = 100,
  LAMBDA = MU,
  MAX.GEN = 150,
  P.RECOMB = 1,
  RECOMB = 0.1,
  P.MUT = 1,
  MUT = 0.005
)

Arguments

data	An object of class goelz.
save.path	A character string indicating the path for where to save data after each generation.
MU	The population size.
LAMBDA	The number of offspring to produce in each generation.
MAX.GEN	The number of generations to run the evolutionary algorithm.
P.RECOMB	The probability of two parents to perform crossover.
RECOMB	The crossover probability for each gene.
P.MUT	The probability to apply mutation to a child.
MUT	The mutation probability for each gene.

Details

While goelz creates Goelz Triangle designs that roughly follow the conformity criterion set forth by Goelz (2001), this function optimizes designs for conformity using an evolutionary algorithm. Function parameters other than data are all controls on the evolutionary algorithm. The ecr package is used for the evolutionary algorithm.

Value

An list containing:

• "layout" - A data frame (tibble) containing the base goelz design.

• "stats" - A data frame (tibble) containing statistics on each generation in the evolutionary algorithm.

• "data" - A data frame (tibble) containing the actual data (designs) of each Goelz Triangle in each generation.
