Averager usage

[sme]

waterID                = WaterClass object
waterColumn            = List of WaterClass objects
phytoID                = PhytoClass object
phytoList              = List of PhytoClass objects
chla, chlb, chlc, caro = instance variables of phytoID
each waterID has a phytoList

I want to calculate the average of each separate pigment (chla..caro)
for each individual species (phytoID) down the water column. i.e. the
Averager object must iterate:

foreach phytoID
   foreach pigment in [chla, chlb, chlc, caro]
      print average across waterColumn
   }
}

My clumsy effort resulted in:

  averageID = [Averager createBegin: [self getZone]];
  [averageID setCollection: waterColumn];
  averageID = [averageID createEnd];
  for (j=0;j<phyN;j++) {
    for (i=1;i<=4;i++) {
      [averageID setProbedSelector: M(getPigments:Species:):(id)i:(id)j];
      [averageID update];
      printf("%e ",[averageID getAverage]);
    }
  }

This leads to a compiler error:

OceanClass.m:481: warning: return type for `setProbedSelector:::' defaults to id

The relevant includes are:
#import <objectbase/SwarmObject.h>
#import <objectbase.h>
#import <simtoolsgui.h>
#import <random.h>
#import <analysis.h>
#import <activity.h>

but the error is probably in the syntax of the setProbedSelector
method. Any help appreciated
