从aheatmap和heatmaply (heatmapr)中删除行标签

Question

我想从具有多行的热图中删除行标签。我需要在 heatmaply 和 aheatmap 中执行此操作。然而，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帧的行名称，并且当行名称为空时，它默认为 rownames= 1:nrow。然而，heatmap.2 适当地处理了这个问题，并将它们从图中一起删除。我可以使用 aheatmap 和 heatmaply 来做到这一点吗？下面是一个可重现的示例：

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，因此一直使用 R 3.2.1）：

aheatmap 产生：

我想要 heatmap.2 的 aheatmap 版本，没有行标签：

Answer 1

尝试热图中的参数

showticklabels

。它控制行和列标签的打印。

例如

showticklabels = c(TRUE, FALSE)

显示列，但不显示行标签。
