In pedantics: Functions to Facilitate Power and Sensitivity Analyses for Genetic Studies of Natural Populations

Description

Prepares a pedigree to conform with requirements of many softwares used in quantitative genetic analysis, as well as for many of the functions in pedantics.

Usage

fixPedigree(Ped, dat = NULL)

Arguments

Ped	An ordered pedigree with 3 columns: id, dam, sire
dat	An optional data frame, the same length as the pedigree

Value

Returns a pedigree in which all individuals that exsit in the dam and sire columns are represented by their own record lines, occurring before the records of their first offspring. If data are supplied, then fixPedigree will return a dataframe, the first two columns are the 'fixed' pedigree, and the following columns of which contain appropriately reordered data.

Examples

##  a valid pedigree, i.e., no loops, no bisexuality, etc.,
## but where not all parents have a record line, and where 
## parents do not necessarily occur before their offspring:
pedigree<-as.data.frame(matrix(c(
  10,1,2,
  11,1,2,
  12,1,3,
  13,1,3,
  14,4,5,
  15,6,7,
  4,NA,NA,
  5,NA,NA,
  6,NA,NA,
  7,NA,NA),10,3,byrow=TRUE))
names(pedigree)<-c("id","dam","sire")

fixedPedigree<-fixPedigree(Ped=pedigree)
