[R] read attribute

[Mulholland, Tom]

Since I'm not sure what you are trying to achieve would ts1 at positions get what you wanted without unclassing the object. I only ask this because my first instinct when I started using the Rmetrics package was to try and use ts1$positions which only gives you a null value.
