My data looks like:

```
x             y  
2             5
3             6
4             2
6             1
7             10
12            16
145           1

```

Looking to output the number that's smaller than the other into a new column which would look like:

```
x             y           z
2             5           2
3             6           3
4             2           2
6             1           1
7             10          7
12            16          12
145           1           1

```

None of the data will be equal so you don't need to worry about that.

```
x <- c(2,3,4,6,7,12,145)
y <- c(5,6,2,1,10,16,1)
df <- data.frame(x,y)

```
