[R-sig-ME] MCMCglmm

[Jarrod Hadfield]

Hi Alex/David,

The insertPed function from MasterBayes can be used to insert the  
missing records, and then it should run fine. prunePed is also useful  
for removing pedigree members which don't contribute any information  
to the analysis.

Cheers,

Jarrod
