Examples

## Not run: 
# load the toy dataset
data( soy ) 

# run gwas
fit1 = gwas(y[w], Z[w,], pop[w]) 
# adjust variances
fit2 = CorrectBeavis( fit1 ) 

# Compare before and after correction
plot( fit1, h2=TRUE, col=8, pch=20) # display QTL h2
plot( fit2, h2=TRUE, add=TRUE, pch=20, type='o') # adjusted QTL h2
legend('topleft',pch=16,col=c(8,1),c('Before correction','After Beavis correction'))

## End(Not run)
