[BioC] GeneticsPed Pedigree object creation error: recursive indexing failed at level 2

[Liz Hare]

Hello,

I'm trying to make a Pedigree object in GeneticsPed.

Data in test2.csv:

id,sire,dam
1,,
2,,
3,,
4,,
5,1,2
6,3,4
7,5,6
8,5,6

R session:

 > tp <- read.csv("test2.csv", header=TRUE)
 > ped.1 <- Pedigree(ped, subject = tp$id, ascendant = c("sire", "dam"))
Error in .subset2(x, i, exact = exact) :
   recursive indexing failed at level 2

==============================================

I also had this problem with R 3.0.1 and GeneticsPed 1.22.0 in 64-bit 
Windows. I've tried it with other pedigrees and it doesn't work there, 
either.

I have read the package documentation and searched the Bioconductor 
site, and not found anything that appears to apply to this situation.

Thanks for any ideas!

Liz
