Hello again.

Following a great idea from Jim and Dennis, I began to use the function
ave() in my big data.
I proved to use this command in my data with FUN=max(x,na.rm=T), and I
received a Warning that translated looks like

Warning in max (x, na.rm = T):
no arguments to max; returning -Inf

Is this happening 'cause I´m using a big table : 254417 rows   9 columns?
