The following selects an entire column in a DataFrame:

```
select(df,:x)

```

But how do I select the second row of x, say?

`select(df, :x)`. That doesn’t select the column, it makes a new `DataFrame` with only one column `:x`. i.e. it doesn’t return the array `df.x`.

For the vector you want

```julia
df.x # doesn't copy the column
df[!, :x] # doesn't copy the column
df[:, :x] # copies the column

```

For the second element you want

```julia
df[2, :x]
df.x[2]

```
