When I got around to running it I was hampered by a lack of knowledge
about what sort of data-object "price" might have been. I tried
putting in a single number on hte theory that it would saitisfy the
seq() call, and also got the error you report. More input is needed
from the OP about the problem specification, and hopefully she will
provide a test dataset.
