Convert the values in a column into row names in an existing data frame（5个答案）
3天前关闭。
我想将第一列指定为行名称kirp.mut。
rownames(kirp.mut) <- kirp.mut[,1]
kirp.mut[,1] <- NULL追溯：
> rownames(kirp.mut) <- kirp.mut[,1]
Error in `.rowNamesDF<-`(x, value = value) : invalid 'row.names' length
In addition: Warning message:
Setting row names on a tibble is deprecated.尺寸：

tibble不能指定行名称。您可以将其转换为其他格式，如数据框，然后指定行名称。您也可以在tibble上使用
column_to_rownames执行此tidyverse解决方案，而无需显式转换为其他格式，但它将在内部执行此操作并返回data.frame：有关行名称和tibble，请参见技术文档here
