And adding to my own posting:
removing the column can be done more elegantly:
frame <- frame[,-1]
And I forgot to mention that now you can say things like
frame['x2',]w
The frame$y2 notation still only works for columns, of course.
Maybe, if you tell us some more about your actual analysis,
more help can be provided.
