Hi

Im using the kinship package to draw a pedigree. On my data set this works fine but when i add indivudals to the pedigree i keep getting an error i hope someone can help me!

This is the code im using:

Data<-read.table("Tree.txt", header=T, sep=",")
attach(Data)
ped<-pedigree(id, dadid, momid, sex, aff)
par(xpd=T)
plot.pedigree(ped)

This is my data looks like without the last 3 individuals it works perfect,when i add them i get the following error:
Error in if (min(pos2) < 0) { : missing value where TRUE/FALSE needed

famid,id,dadid,momid,sex,aff

1,20670,9979,8862,1,0

I tried putting nuclear families closer together in de pedigree but this doesn't seem to help. All individuals have both parents in the pedigree or have 2 missing parents.


I hope someone can help me with this!
