これらのデータフレームをRでバインドできないのはなぜですか？

Question

私はRで2つのデータフレームをrbindしようとしていますが、「重複した」row.names 'は許可されていません。それらは、それぞれ100行と同じ数の列を持つ2つのデータフレームです。 rbindを使う前に行の名前を定義しようとしましたが、まだエラーが出ます。私はこれを使用しています：

row.names(sons) <- make.names(1:100, unique=TRUE) 
row.names(sons2)<-make.names(101:200, unique = TRUE) 
sons3 <- rbind(sons, sons2) 

私のデータは、UK Companies CompaniesのAPIに由来しています。配列内のエントリは次のようになります。

description_identifier     kind      title company_type 
X1   dissolved-on searchresults#company THIS IS A COMPANY NAME   ltd 
       self        snippet date_of_cessation 
X1 /company/08733334 Unit 2, 41 A Road, London, E8 2QH  2015-11-10 
           description date_of_creation company_number company_status 
X1 08730034 - Dissolved on 10 November 2015  2013-10-14  08730034  dissolved 

これらのデータフレームをどのようにバインドできますか？

EDIT：要求され、dputのための出力（ヘッド（息子が））

Answer 1

だとして、あなたのリンク変数があることが表示されます問題の核心であるdata.frameとして保存されます。これを修正するには、以下を使用します。

sons$links <- as.character(unlist(sons$links)) 
sons2$links <- as.character(unlist(sons2$links)) 

また、完全rownamesを削除する必要があります。

row.names(sons) <- NULL 
row.names(sons2)<- NULL 
sons3 <- rbind(sons, sons2) 

あなたがそれらを維持したい場合は、最初のベクトルとして保存します。さらに、
