Dear all

I have a data.frame with 915 rows and 7 columns and I want to aggregate
one of the variables using 'aggregate.data.frame': 

my.new.data <- aggregate.data.frame(my.data$VAR1, by =
list(my.data$VAR2,...,my.data$VAR7), FUN = max)

however I get the message: "Error: vector memory exhausted (limit
Since I didn't set a limit I assume that's the machine memory (516 MB +
130 MB of swap). Is this normal for a data.frame of those dimensions?
