[R] How to add specific column to data.set?

[R. Michael Weylandt]

Ok, so you simply need to use the methods David or I provided -- it
looks like you don't even have to change the variable names...

Is there something that isn't clear now?

Also, reproducible examples are much better if you use dput() so they
are actually reproducible....
