family: Find families (lines) in the pedigree
In GeneticsPed: Pedigree and genetic relationship functions

Description Usage Arguments Details Value Author(s) See Also Examples

family classifies individuals in the pedigree to distinct families or lines. Two individuals are members of one family if they have at least one common ascendant. family<- provides mean to properly add family information into the pedigree.

1 2	family(x) family(x, col=NULL) <- value

`x`	pedigree object
`col`	character, column name in `x` for family
`value`	family values for individuals in the pedigree

col provides a mean to name or possibly also rename family column with user specified value, say "familia" in Spanish. When col=NULL, which is default, "family" is used.

A vector of family values (integers)

Pedigree

  ## Two families examples
  ped <- data.frame(    id=c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11),
                    father=c(0, 0, 0, 0, 0, 0, 5, 1, 3,  8,  7),
                    mother=c(0, 0, 0, 0, 0, 0, 6, 2, 4,  9, 10),
                generation=c(1, 1, 1, 1, 1, 1, 2, 2, 2,  3,  4))
  ped <- Pedigree(ped, unknown=0, generation="generation")
  family(ped)

  ## After break we get two families
  ped1 <- removeIndividual(ped, individual=11)
  family(ped1)

  ## Subsetting can also be used
  family(ped[1:10,])
  family(ped[7:10,])

  ## Pedigree need not be sorted in advance
  ped2 <- ped[sample(1:10), ]
  family(ped2)

  ## Assign family values to pedigree
  family(ped) <- family(ped)
  ped
  family(ped, col="familia") <- family(ped)
  ped
