我想从包含多行的热图中删除行标签。我需要在热图和热图中都这样做。但是，我能想到的所有可能选项要么导致错误，要么从 1:nrow 重新标记行并显示数字。我假设这是因为热图使用矩阵或数据框的行名，当行名为空时，它默认为行名 = 1:nrow。但是，heatmap.2 会适当地处理这个问题，并将它们一起从图中删除。我可以用 aheatmap 和 heatmaply 做到这一点吗？一个可重现的例子如下：
library(NMF)
library(heatmaply)
library(pheatmap)
library(gplots)
NMF::aheatmap(mtcars,labRow="") # numbers as rownames & row labels
NMF::aheatmap(mtcars,labRow=NA) # numbers as rownames & row labels
heatmaply(mtcars,labRow="")
# Error in `rownames<-`(`*tmp*`, value = "") :
# length of 'dimnames' [1] not equal to array extent heatmaply(mtcars,labRow=FALSE)
# Error in `rownames<-`(`*tmp*`, value = "") :
# length of 'dimnames' [1] not equal to array extent heatmaply(mtcars,labRow=NULL) # numbers as rownames & row labels
# including pheatmap just in case this does work, but it doesn't
pheatmap::pheatmap(mtcars, labels_row=FALSE) # NA as rownames pheatmap::pheatmap(mtcars, labels_row="") # NA as rownames pheatmap::pheatmap(mtcars,labRow=FALSE) # does not remove rownames
heatmap.2(as.matrix(mtcars),labRow="") # works
我尝试在 Mac 和具有最新 R 操作系统的 Windows 上运行它。这是我的 mac 会话信息（无法升级操作系统，因此卡在 R 3.2.1 中）：
