Re: [R] Error in Aggregate
The error message is clear: your problem is that your data.frame (note the period) contains factors. Use str(data) -- also don't use data as it's a function name -- to see which ones and change as appropriate.

[R] Error in Aggregate function
Hi, When I run the Aggregate function in repeat loop, I got the following error: Error in sort.list(unique.default(x), na.last = TRUE) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list? How to solve this error. Anyone can help me. Urgent. Thanks.
