My data looks something like this:

```
> head(my_data,n=8)
Subject Group Value1 Value2 Outcome
1 A 12.404 5.00 1.33
2 A 14.898 4.34 6.77
3 A 13.870 2.53 5.01
4 A 14.313 9.33 6.82
5 B 13.407 4.99 8.42
6 B 13.480 2.59 9.11
7 B 13.761 1.42 8.21
8 B 12.607 0.55 8.32
...
...
```

I'm interested in performing a mixed linear effects model with a comparison between the Groups. I want to see the effect the group difference has on the different fixed variables (i.e. Value1 and Value2). I wasn't sure how to go about that. Initially this is what I had:

```
lme(outcome*Group~ (Value1+Value2)*Group, random= ~ 1|Subject, data=my_data)
```

But once I read further, I thought it should look something like this:

```
lme(outocme~Value1+Value2+Group, random=1|Subject, data=my_data)
```

However, when I do that I get an output that only lists group A but not group B for some reason.

Any help/guidance would be greatly appreciated.

Thanks.
