Errorincustom_hovertext[rowInd,colInd,drop=FALSE]:subscript out of bounds Is there a way for me to createcustom_textinheatmaply()that specifies hover text information given per each column of the heatmap, as opposed to global information given to each heatmap square?
关于ggplot2:如何在r中的热图单元格中显示数字单元格值 | 珊瑚贝 How to show the numeric cell values in heat map cells in r 我正在尝试创建一个热图,以显示驱动每个单元格中颜色的值。如果一个单元格是深蓝色的,因为它有 5 个观察值,我想查看该单元格中的数字 5。 (目的是建立一个信用评级迁移矩阵,其...

In this post, I will describe how to use R to build heatmaps. The ggplot2 package is required for this, so go ahead and install it if you don’t already have it. You can install it using the following command:install.packages('ggplot2') ...
