Using theheatmap()function Theheatmap()function is natively provided in R. It produces high quality matrix and offers statistical tools to normalize input data, run clustering algorithm and visualize the result with dendrograms. It is one of the very rare case where I prefer base R toggplot2...
R base heatmap: heatmap() The built-in R heatmap() function [in stats package] can be used. A simplified format is: heatmap(x, scale = "row") x: a numeric matrix scale: a character indicating if the values should be centered and scaled in either the row direction or the column ...

R语言 heatmap()用法及代码示例heatmap()R语言中的函数用于绘制热图。热图被定义为数据的图形表示,使用颜色来可视化矩阵的值。在这种情况下,为了表示更常见的值或更高的活动,使用较亮的颜色,本质上使用红色,而不太常见或活动值更深的颜色是首选。热图也由着色矩阵的名称定义。 用法: heatmap(data) 参数:data:...
A package for drawing pretty heatmaps in R. The ordinary heatmap function in R has several drawbacks when it comes to producing publication quality heatmaps. It is hard to produce pictures with consistent text, cell and overall sizes and shapes. The function pheatmap tries to alleviate the ...
