 5  
 6  Given the filename as a **String** and a **BitVector**, convert the
 7  vector into a **DataFrame** and save the result as an **Arrow** file.
 8  The vector is expected to consist of the **boolean** type.  The **DataFrame**
 9  column name is set to **OR_result**.
10  
11  This function depends on these packages:
12  - Arrow
13  - DataFrames
14  
15  ## Examples
16  
17  ```julia-repl
18  julia> bitvec2arrow("C:\\User\\Data\\mydata.arrow", BitVector([true, true, false]))
19  ```
20  
21  The DataFrame is generated as:
22  ```shell
23  3×1 DataFrame       
24   Row │ OR_result 
25       │ Bool
26  ─────┼──────────────
27     1 │         true 
28     2 │         true 
29     3 │        false 
30  ```
