Well you didn't tell us how you fit gridge and I'm not sure if you meant for that first output to be gridge or gridge1. Also please wrap your code in [code][/code] tags so that indentation is preserved. But mainly if you're going to ask a question like this you need to provide all the relevant details. In this case that means we need to know how you fit the first model.
But it sounds like you need to read up on ridge regression a little more because one shouldn't expect the exact same results if you use a different value for lambda.
