Hi,
It's a bit hard to read what you have provided (don't forget that code pasted
into emails on this list are best rendered if the email client is configured
for plain text not html), but I suspect that it there is no %*%t. Instead, I
think it should look like...
x %*% t(y)
where your x is 'mod7' and your y is all that other stuff. You might try ...
prediction = plogis( as.matrix( mod7 %*% t(ab) ) )
but that's just a guess.
