All functions

SimPed(): SimPed (Deprecated)

adjustKidsPerCouple(): Generate or Adjust Number of Kids per Couple Based on Mating Rate

allGens(): allGens A function to calculate the number of individuals in each generation. This is a supporting function for simulatePedigree.

assignCoupleIds(): Assign Couple IDs

buildBetweenGenerations(): Process Generation Connections

buildWithinGenerations(): Process Generations for Pedigree Simulation

calculateH(): Falconer's Formula Use Falconer's formula to solve for H using the observed correlations for two groups of any two relatednesses.

calculateRelatedness(): Calculate Relatedness Coefficient

checkIDs(): Validates and Optionally Repairs Unique IDs in a Pedigree Dataframe

checkSex(): Validates and Optionally Repairs Sex Coding in a Pedigree Dataframe

comp2vech(): comp2vech Turn a variance component relatedness matrix into its half-vectorization

createGenDataFrame(): Create Data Frame for Generation

determineSex(): Determine Sex of Offspring

dropLink(): dropLink A function to drop a person from his/her parents in the simulated pedigree data.frame. The person can be dropped by specifying his/her ID or by specifying the generation which the randomly to-be-dropped person is in. The function can separate one pedigree into two pedigrees. Separating into small pieces should be done by running the function multiple times. This is a supplementary function for simulatePedigree.

evenInsert(): evenInsert A function to insert m elements evenly into a length n vector.

famSizeCal(): famSizeCal A function to calculate the total number of individuals in a pedigree given parameters. This is a supporting function for function simulatePedigree

fitComponentModel(): fitComponentModel Fit the estimated variance components of a model to covariance data

hazard: Simulated pedigree with two extended families and an age-related hazard

identifyComponentModel(): identifyComponentModel Determine if a variance components model is identified

inbreeding: Artificial pedigree data on eight families with inbreeding

inferRelatedness(): Infer Relatedness Coefficient

makeInbreeding(): makeInbreeding A function to create inbred mates in the simulated pedigree data.frame. Inbred mates can be created by specifying their IDs or the generation the inbred mate should be created. When specifying the generation, inbreeding between siblings or 1st cousin needs to be specified. This is a supplementary function for simulatePedigree.

makeTwins(): makeTwins A function to impute twins in the simulated pedigree data.frame. Twins can be imputed by specifying their IDs or by specifying the generation the twin should be imputed. This is a supplementary function for simulatePedigree.

markPotentialChildren(): Mark and Assign children

ped2add(): Take a pedigree and turn it into an additive genetics relatedness matrix

ped2ce(): Take a pedigree and turn it into an extended environmental relatedness matrix

ped2cn(): Take a pedigree and turn it into a common nuclear environmental relatedness matrix

ped2com(): Take a pedigree and turn it into a relatedness matrix

ped2fam(): Add an extended family ID variable to a pedigree

ped2graph(): Turn a pedigree into a graph

ped2maternal(): Add a maternal line ID variable to a pedigree

ped2mit(): Take a pedigree and turn it into a mitochondrial relatedness matrix

ped2paternal(): Add a paternal line ID variable to a pedigree

plotPedigree(): plotPedigree A wrapped function to plot simulated pedigree from function simulatePedigree. This function require the installation of package kinship2.

potter: Fictional pedigree data on a wizarding family

related_coef(): related_coef (Deprecated)

relatedness(): relatedness (Deprecated)

repairIDs(): Repair Missing IDs

repairSex(): Repairs Sex Coding in a Pedigree Dataframe

resample(): Resample Elements of a Vector

simulatePedigree(): Simulate Pedigrees This function simulates "balanced" pedigrees based on a group of parameters: 1) k - Kids per couple; 2) G - Number of generations; 3) p - Proportion of males in offspring; 4) r - Mating rate.

sizeAllGens(): sizeAllGens An internal supporting function for simulatePedigree.

vech(): vech Create the half-vectorization of a matrix
