Naming your columns / rows

Let's look at cash again:

cash

  comp cash yr
1    A 1000  1
2    A 4000  3
3    A  550  4
4    B 1500  1
5    B 1100  2
6    B  750  4
7    B 6000  5

Wait, that's not right! It looks like someone has changed your column names! Don't worry, you can change them back using colnames() just like you did with names() back with vectors.

Similarly, you can change the row names using rownames(), but this is less common.
