演算子を使用して配列に新しい値を追加する方法について、この情報を見つけました。ただし、これをrmongodb$pushで機能させることはできないようです。
DBに次のドキュメントがあるとします
_id : 7 51005201f8ab44f1690f9526
tags : 4
1 : 2 a
2 : 2 b
3 : 2 c
配列に値を追加したいのですがtags。これが私が試したことです：
q <- mongo.bson.from.list(list(tags="a"))
1を試す
ここでは、$push演算子を使用してみました
コード
bnew <- mongo.bson.from.list(list("$push"=list("tags"="d")))
> mongo.update(mongo=con, ns, criteria=q, objNew=bnew)
[1] FALSE

10genのTadMarshallがバグレポートへのコメントで示唆しているように、MongoDBサーバーをモードで実行して（BSON構造を検証）、ドキュメントを挿入するコードを再実行しまし--objcheckた。サーバーはドキュメントを挿入できません。失敗したアサーションが原因です。フラグなしでサーバーを実行すると--objcheck、挿入は成功します（ただし、これはおそらく検証が行われないという事実によるものです）。
tags最初のコードで、IMHOがMongoDBのインデックス付け規則と同期していないというドキュメントが作成されたため、2つの異なるバージョンの配列を組み合わせてみました。
（潜在的に）無効なドキュメント
それが私が上でそれをした方法です。配列インデックスが。で始まることを確認していないことに気づきました0。このドキュメントの挿入は失敗します（以下のログファイルを参照）
buf <- mongo.bson.buffer.create()
mongo.bson.buffer.start.array(buf, name="tags")
values <- list("a", "b", "c")
for (ii in seq(along=values)) {
mongo.bson.buffer.append(
buf=buf,
name=as.character(ii),
value=values[[ii]]
)
}
mongo.bson.buffer.finish.object(buf) # finish array 'tags'
mongo.bson.buffer.finish.object(buf) # finish buffer
b <- mongo.bson.from.buffer(buf)
> b
tags : 4
1 : 2 a
2 : 2 b
3 : 2 c
有効なドキュメント
インデックスがで始まることを確認した0ので、これは間違いなく有効なBSONドキュメントである必要があります。ただし、このドキュメントの挿入も失敗します（以下のログファイルを参照）
buf <- mongo.bson.buffer.create()
mongo.bson.buffer.start.array(buf, name="tags")
values <- list("a", "b", "c")

buf=buf,
