I'm following the latin-squares example at

When I run that dataset, the ssq vector returned from get_ssq is:


The Type III sums of squares given in the example are:

Source                  Type III SSQ
Corrected Model         263.064
Intercept               815.102
A                       78.869 
B                       28.599 
C                       155.596
Error                   66.563 
Total                   1144.730 
Corrected Total         329.628

So we can see that the first two items in the vector correspond to the SSQ for 
"Error" and "A" respectively.  The other items don't seem to match anything.  
How do we get the sums of squares for "B" and "C" ?
