I got one for you guys!

I have 2 data frames, the rownames for both are identical

df1 is 16x1

df2 is 16x785

I want to take each column of df2 and divide it by df1, then take the log of this value and store in a new df3

so, example, lets say df1 and df2 looked like this:

```
df1 df2
[one] [one] [two] [three]
[A] 5 [A] 10 5 15
[B] 7 [B] 7 14 21
[C] 9 [C] 9 9 18
```

The resulting data would look like this after division, with the same dimensions as df2:

```
[one] [two] [three]
[A] 2 1 3
[B] 1 2 3
[C] 1 1 2
```

Then the log of this is easy of course.

I tried dividing df2/df1 and got the old: `'/' only defined for equally-sized data frames`

error

Thanks in advance!
