MetaTally
combines multiple tallies:
In[1]:=
[◼]
MetaTally
[{Tally[{1,1,1,2}],Tally[{1,2,2}]}]
Out[1]=
{{1,4},{2,3}}
Analogous to the
Tally
of the combined lists:
In[2]:=
Tally[Join[{1,1,1,2},{1,2,2}]]
Out[2]=
{{1,4},{2,3}}
———
Allowing work with intermediate tallies:
In[29]:=
catGenderTally=Tally[{"F","F","F","F","F","M","M","M"}]
Out[29]=
{{F,5},{M,3}}
In[33]:=
dogGenderTally=Tally[{"M","M","M","M","F"}]
Out[33]=
{{M,4},{F,1}}
In[34]:=
[◼]
MetaTally
[{catGenderTally,dogGenderTally}]
Out[34]=
{{F,6},{M,7}}
