Why and how exactly you use aggregate in loop?

Using this weird construction on my data I do not get any error.

for (i in 2:5) print(aggregate(zeta[,i], list(zeta[,"dus"]), mean)) 
  Group.1        x
1     ano 6.865000
2      ne 6.592727
  Group.1        x
1     ano 6.785000
2      ne 6.635455
  Group.1         x
1     ano 0.9426667
2      ne 0.5016364
  Group.1        x
1     ano 1.345167
2      ne 1.183727

Please provide at least a code, better with some simple fake data.

Regards
Petr
