[R-sig-ME] D relationship matrix

[Jarrod Hadfield]

Hi Craig,


I'm not aware of anything in R but I believe Ignacy Misztal's fotran  
routines http://nce.ads.uga.edu/~ignacy/newprograms.html or Per Madsen  
and Just Jensen's DMU package http://www.dmu.agrsci.dk/ will calculate  
D and presumably D-1. Hoeschele & van Raden (J. Dairy Science  
74:557-569) provide a recursive algorithm for D-1 in the absence of  
inbreeding and this may not be that hard to implement.

Cheers,

Jarrod
