In the following code I get a warning at the line indicated with the 
arrow ("--->"). The warning is:

"warning: assignment from incompatible pointer type."  I thought 
using an "id" declaration would avoid this kind of thing.


-(NSArray *)shiftObjectsInArray: (NSMutableArray *)anArray {
   int        x;
   id        *roller;
   
   if ([anArray count] > 0) {
--->        roller = [anArray lastObject];
       for (x = [anArray count]; x = 1; x--) {
           [anArray replaceObjectAtIndex: x withObject: [anArray 
objectAtIndex: x-1]];
       }
       [anArray replaceObjectAtIndex: 0 withObject: roller];
       return anArray;
   } else {
       return nil;
   }
}


Basically, what I am trying to accomplish is a "shift and roll" of 
the objects in "anArray." I want to shift every object to the next 
higher position and "roll" the last object to the first position in 
the array.
