r - 在文件 .txt 中写入数据帧

Question

当我使用以下命令编写数据帧时：

write.table(dfArticles,"C:/Biology.txt",append = FALSE,sep=",",dec=".")

我得到以下结果：

"Title","Authors","AuthorAffiliations","CorrespondenceAuthor","PublishDate","Abstract","Keywords"
"1","Characterisation of genetic regulatory effects for osteoporosis risk variants in human osteoclasts","Benjamin H. Mullin,Jennifer Tickner,Kun Zhu,Jacob Kenny,S ..................

文件“Biology.txt”在每一行的开头都包含了值“1”“2”“3”……。

为什么包括数字？

Answer 1

我们可以使用row.names = FALSE论据。

write.table(dfArticles,"C:/Biology.txt",append = FALSE,sep=",",dec=".",row.names=FALSE)
