简言之
colormat
rownames
rownames(colormat) <- rownames(colormat)
之后这个答案开始触及问题的本质,但没有深入探讨原因或方式
pheatmap
这个问题的性质与
返回行号的默认向量;每个元素都是一个数值,但表示为一个字符串,因此第10行成为行名“10”。使用时
attributes(colormat)
,你会看到
$row.names
之前是数值向量吗
行名称(colormat)<-行名称(colormat)
和后面的字符向量(它现在有行名)。我不清楚为什么在没有设置行名称的情况下返回任何内容(NULL或NA除外)。

问题不在于行名的数值与字符值,而在于是否设置了行名。如果您执行了以下操作:
rownames(colormat) <- 1:nrow(colormat)
你会发现这也会解决这个问题,就像
船名
属性(colormat)
输出)。
如果你使用
tibble::has_rownames(colormat)
行名称(colormat)<-行名称(colormat)
FALSE
. 完成作业后,你将获得
TRUE
tibble::has_rownames(colormat)
## [1] FALSE
rownames(colormat) <- rownames(colormat)
tibble::has_rownames(colormat)
## [1] TRUE
野鸡图
但在内部,它一定遇到了这个问题
船名
没有被设定。如果您联系此软件包的作者(可能通过GitHub:
