Eu quero poder passar uma sequência deoption float ao RProvider emF#. Se eu tiver uma sequência de carros alegóricos comSome float eNone, como posso obter oNone valores emR com oRProvider? Eu teria esperado oNones seria equivalente a umNA valor emR, mas não consigo passar umseq<option float> para R.

Por exemplo, com

open System
open RDotNet
open RProvider
open RProvider.graphics
open RProvider.stats  

let optData4 = 
    seq [Some 10.0; Some 9.0; Some 8.0; None; Some 6.0; 
        Some 5.0; Some 5.0; None; Some 4.0; Some 2.0; 
        None]

let testData4 = 
    namedParams [
        "regPrice", optData4;]
    |> R.data_frame

Eu recebo um erro de várias linhas:

A única maneira de passar alguma coisa para oRProvider é se eu converter oseq<option float> para umseq<float> com

let optData4 = 
    seq [Some 10.0; Some 9.0; Some 8.0; None; Some 6.0; 
        Some 5.0; Some 5.0; None; Some 4.0; Some 2.0; 
        None]
    |> Seq.choose id

let testData4 = 
    namedParams [
        "regPrice", optData4;]
    |> R.data_frame

mas isso nega o propósito de ter a opção None (que, eu pensaria, seria comparável aRs NA valor.

Como posso passar uma sequência de valores para oRProvider onde alguns dos valores sãoNone noF# e deve serNA noR?
