cross_simulate: Simulate an autopolyploid full-sib population

In mmollina/MAPPoly: Genetic Linkage Maps in Autopolyploids

Simulate an autopolyploid full-sib population

Description

Simulate an autopolyploid full-sib population with one or two informative parents under random chromosome segregation.

Usage

cross_simulate(
  parental.phases,
  map.length,
  n.ind,
  draw = FALSE,
  file = "output.pdf",
  prefix = NULL,
  seed = NULL,
  width = 12,
  height = 6,
  prob.P = NULL,
  prob.Q = NULL
)

Arguments

parental.phases	a list containing the linkage phase information for both parents
map.length	the map length
n.ind	number of individuals in the offspring
draw	if TRUE, draws a graphical representation of the parental map, including the linkage phase configuration, in a pdf output (default = FALSE)
file	name of the output file. It is ignored if draw = TRUE
prefix	prefix used in all marker names.
seed	random number generator seed (default = NULL)
width	the width of the graphics region in inches (default = 12)
height	the height of the graphics region in inches (default = 6)
prob.P	a vector indicating the proportion of preferential pairing in parent P (currently ignored)
prob.Q	a vector indicating the proportion of preferential pairing in parent Q (currently ignored)

Details

parental.phases.p and parental.phases.q are lists of vectors containing linkage phase configurations. Each vector contains the numbers of the homologous chromosomes in which the alleles are located. For instance, a vector containing (1,3,4) means that the marker has three doses located in the chromosomes 1, 3 and 4. For zero doses, use 0. For more sophisticated simulations, we strongly recommend using PedigreeSim V2.0 https://github.com/PBR/pedigreeSim

Value

an object of class mappoly.data. See read_geno for more information
