I am trying to subset a dataframe’s (DF) columns using a list of column names extracted using `DataFrames.Terms(model_formula).terms`

which returns a type of `Any`

object. I would like to convert this type `Any`

to `Symbol`

so I can subset a DF as indicated below;

**This works fine;**

```
using DataFrames
df = DataFrame()
df[:y] = randn(10)
df[:x1] = randn(10)
df[:x2] = randn(10)
name_list = [:x1, :x2]
df[name_list]
```

**However, this does not work as input_covariates is of type Any and produces following method mismatching error.**

Any idea how to achieve my goal here??Thanks.

```
model_formula = y ~ x1 + x2
input_covariates = DataFrames.Terms(model_formula).terms
df[input_covariates]
```
