hybridCross: Hybrid crossing

Description

A convience function for hybrid plant breeding simulations. Allows for easy specification of a test cross scheme and/or creation of an object of HybridPop-class. Note that the HybridPop-class should only be used if the parents were created using the makeDH function or newPop using inbred founders. The id for new individuals is [mother_id]_[father_id]

Usage

hybridCross(females, males, crossPlan = "testcross",
  returnHybridPop = FALSE, chunkSize = 10000, simParam = NULL)

Arguments

females

female population, an object of Pop-class

males

male population, an object of Pop-class

crossPlan

either "testcross" for all possible combinantions or a matrix with two columns for designed crosses

returnHybridPop

should results be returned as HybridPop-class. If false returns results as Pop-class. Population must be fully inbred if TRUE.

chunkSize

when using returnHybridPop=TRUE, this parameter determines the maximum number of hybrids created at one time. Smaller values reduce RAM usage, but may take more time.

simParam

an object of SimParam

Examples

# NOT RUN {
#Create founder haplotypes
founderPop = quickHaplo(nInd=10, nChr=1, segSites=10, inbred=TRUE)

#Set simulation parameters
SP = SimParam$new(founderPop)

#Create population
pop = newPop(founderPop, simParam=SP)

#Make crosses for full diallele
pop2 = hybridCross(pop, pop, simParam=SP)

# }
