Hi,

I have a function that takes a variable number of arguments like the following:

```julia
function view(vargs...)
  out = DataFrame(vargs)
  out
end

```

I want the ouput of `view` to be the same as if I was using `DataFrame`, example:

```julia
DataFrame(Symbol("Period") => ["T", "T-1"], Symbol("Type") => [1, 2])

```

same as

```julia
view(Symbol("Period") => ["T", "T-1"], Symbol("Type") => [1, 2])

```

I am missing an operation inside `view` to “un-vectorise” the inputs. Would you please be able to help?

Thank you

I think you want splat:

```julia
view(args...) = DataFrame(args...)

```

Note that `f([1,2,3]...) === f(1,2,3)`.

You’re looking for `...` 🙂

```julia
function view(vargs...)
  out = DataFrame(vargs...)
  out
end

```

`...` in a function definition “slurps” up multiple arguments, whereas it “splats” them when used in a call.
