...pe etc, or that there is an error in the sampler itself?
> s2eg2=1/rgamma(mg2,(12/2),.5*t(residuals(lm(yg[,1]~xg-1))%*%residuals(lm(yg[,1]~xg-1))))
> for(i in 1:mg2){
+ s2yg[i,]=parsy+t(rnorm(1,mean=0,sd=s2ygscale[i])%*%chol(s2eg2[i]*xgtxgi))
+ write(c(s2yg[i,],s2eg2[i]),

I GET A BUNCH OF NUMBERS PRINTED HERE, THE OUTPUTTED VALUES WHICH ALSO
APPEAR IN A TEXT FILE. I HIT ABOUT 2000 VALUES, THEN I GET THIS MESSAGE:
Error in s2yg[i, ] = parsy + t(rnorm(1, mean...
