pedigreeDeleteDuplicates removes duplicates from a pedigree.

1	pedigreeDeleteDuplicates(pedigree, duplicates)

`pedigree`	A dataframe containing the pedigree information for the samples to be examined with columns labeled "family", "individ", "mother", "father" and "sex" containing the identifiers of the family, individual, individual's mother, individual's father and individual's sex (coded as "M" or "F") .
`duplicates`	dataframe with columns "family" (family id) and "individ" (individual id).

The output of pedigreeCheck can be provided to pedigreeDeleteDuplicates in order to generate a new pedigree with duplicates removed.

The output of pedigreeDeleteDuplicates is a pedigree identical to pedigree, but with duplicates removed.
