Question

请您查看下面的代码。当我使用row.names = 1加载数据时，它会抱怨重复的row.names。但是，如果我尝试删除它们，data.frame的维度是相同的??

> Seqbuster <- read.csv(file="IsomiR_Robin.csv",row.names=1,sep="\t",header=T)

Error in read.table(file = file, header = header, sep = sep, quote = quote,  : 
  duplicate 'row.names' are not allowed

Seqbuster <- read.csv(file="IsomiR_Robin.csv",sep="\t",header=T)

> dim(Seqbuster)
[1] 23245    20

> Seqbuster <- unique(Seqbuster)

> dim(Seqbuster)
[1] 23245    20


> head(Seqbuster)

Answer 1

您没有使用unique（）删除第一行中的重复项。使用'1'作为row.names的参数将创建一个dataID，其中您的GeneID作为行名称。您会发现唯一的（Seqbuster $ GeneID）将小于23245。

从数据框中删除重复的row.names
