从heatmapr和heatmaply中删除行标签(heatmapr)

Question

我想从包含很多行的热图中删除行标签。我需要在heatmaply和一个aheatmap中做到这一点。然而，我能想到的所有可能的选项要么导致错误，要么从1:nrow重新标记行并显示内部数字。我假设这是因为热图使用了矩阵或数据框的行名，当行名为空时，它缺省为rownames= 1:nrow。然而，heatmap.2对此进行了适当的处理，并将它们一起从图中删除。我可以使用aheatmap和heatmaply来做这件事吗？下面是一个可重复使用的示例：

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

我尝试过在mac和安装了最新R操作系统的windows上运行这个程序。这是我在mac上的会话信息(不能升级OS，所以坚持使用R 3.2.1)：

aheatmap产生：aheatmap with row NUMBERS

我想要aheatmap版本的heatmap.2，没有行标签：heatmap.2 not so pretty but no row labels

Answer 1

尝试在heatmaply中使用参数showticklabels。它控制行和列标签的打印。
