Hello everybody!

I am trying to export only the numeric data of the result of the variable `r`

to a `.CSV`

. The model does not give an error, but I cannot export the data as I need it.

I would like the data to be written in `.CSV`

this way

```
│ Row │ value │
│ │ Int64 │
├─────┼───────┤
│ 1 │ 0 │
│ 2 │ 0 │
│ 3 │ 0 │
│ 4 │ 0 │
```

However it is written this way for `.CSV`

```
│ Row │ value │
│ │ String │
├─────┼─────────────────┤
│ 1 │ r:2 dimensions: │
```

Why can’t I export the data the way I want?

As the model is, it may not make much sense because it is a cut out of a model that I am building.

Thank you!

```

Modeltest = Model(solver = GLPKSolverMIP())
a = 1:4
t = 1:4
w = 1:2

T = t
W = w
