R Question

I have the data frame having the following format:

`state1 state2 score`

A A 3

A B 13

A C 5

B A 1

B B 0

B C 0

C A 5

C B 6

C C 3

I would like to convert it into a table having the format

`A B C`

A 3 13 5

B 1 0 0

C 5 6 3

Is there an easy way of doing it instead of creating it manually?

Answer

We can do this with `xtabs`

```
xtabs(score~state1+state2, df1)
# state2
#state1 A B C
# A 3 13 5
# B 1 0 0
# C 5 6 3
```
