aggregate function not working?

jcrosbie
The aggregate function for some reason will now work for me.

The error I'm getting is:
"Error in sort.list(y) : 'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?"



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

Price list dataframe:
dput(PriceList)
structure(list(Price = c(0, 8.18, 8.27, 10.42, 10.5, 10.6, 11.13,

Re: aggregate function not working?

In reply to this post by jcrosbie
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.

You have managed to create a slightly pathological dataframe:

 > str(PriceList)
'data.frame': 161 obs. of  3 variables:
  $ Price  : num  0 8.18 8.27 10.42 10.5 ...
  $ Size   : int  664640 440 407 180 690 851 190 480 720 74 ...
  $ bandNum:List of 161
   ..$ : int 0
   ..$ : num 2
   ..$ : num 2
   ..$ : num 3
   ..$ : num 3
   ..$ : num 3
   ..$ : num 3
   ..$ : num 3
   ..$ : num 3
   ..$ : num 3
snipped three pages of output

Try this:

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