Creates and stores an object containing a pedigree in much the same way as the 'pedigree' function of the 'kinship2' package. It is checked that the input represents a correct pedigree. The main differences is that a person is allowed to have one parent present and one absent in the pedigree. Another difference is that no disease parameters are included. The result is an object with class FamiliasPedigree

By default the same prior probability is assigned to all pedigrees in the list, but this can be adjusted with the function parameters. It is computed which persons are common to all the pedigrees listed, and they are handled in a special way: It is with relation to these persons that the number of generations and other parameters are computed. Also, the function will search for and remove pedigrees that are "equivalent" in terms of representing the relationship between these core persons. So if another pedigree is added, with all new persons, the function will return with an error message.

plot.FamiliasPedigree

Plotting function for FamiliasPedigree objects
The function piggybacks the plot function for pedigree objects from the kinship2 package to create a plotting function for FamiliasPedigree objects. Before conversion to a pedigree object, additional parents are added to the pedigree so that each person has either zero or two parents within the pedigree.
