[R-sig-ME] MCMCglmm and estimated breeding values

[Jarrod Hadfield]

Hi,

rbv does not provide estaimted breeding values it simulates random  
breeding values down a pedigree (conditional on the genetic  
(co)variances provided).

To get the posterior distribution of breeding values you need to use  
MCMCglmm and specify pr=TRUE (this saves the random effects including  
the breeding values).

Cheers,

Jarrod
