Warning message with aggregate function
Dear all,
When I use aggregate function as:
attach(warpbreaks)
aggregate(warpbreaks[, 1], list(wool = wool, tension = tension), sum)
The results are right but I get a warning message:
"number of items to replace is not a multiple of replacement length."
BTW: I use R version 2.4.1 in Ubuntu 7.04.
Your kind solutions will be great appreciated.
Best wishes
Yours, sincerely,
Xingwang
