I am trying to create a confusion matrix of an experiment.

So the dataset is like this;

```
    Responses   Condition
3    1             R
4    1             R
6    1             R
7    1             R
8   -1             R
9   -1             N
10  -1             N
11  -1             N
12  -1             R
13   1             R

```

I want to categorize four different conditions; and I want to count each one of the conditions.

1 & N,
-1 & N,
 1 & R,
-1 & R

I want to count each one of those situations in the dataframe.

I have tried to use .itertuples , but I don't know how to use it with 2 parameters.
