[R] aggregate function not working?

[Sarah Goslee]

If you read the error message carefully and look at the data you
included with dput() (for which I thank you!), you'll see that bandNum
is a list, not a vector, just as the error message told you.

I'm not sure how you created or imported your data frame, but
something appears to have not worked the way you expected.

agPriceList=aggregate(PriceList$Size, list(unlist(PriceList$bandNum)),sum)

will work, but you should probably look into correcting your data frame.
