R heatmap.2带颜色键的一排热图 [英] R heatmap.2 One row heatmap with color key

问题描述

我是R的新手，我想使用heatmap.2从我的数据生成单行热图，如图3C中的宽动态DNA甲基化反应"(Dowen等人，2012)中所述. .以下是文章的链接:pnas.org/content/109/32/E2183/1

I'm new to R and i want to generate a one row heatmap from my data using heatmap.2 as reported in "Widespread dynamic DNA methylation in response to biotic stress", Figure 3C (Dowen et al., 2012). The following is a link to the article: pnas.org/content/109/32/E2183/1

我的有效数据只是一列，其值在-1和1之间:

My effective data is just a column with values between -1 and 1:

   deltaMeth
     -1
     -1
    -0.9
    -0.8
    -0.2
     0.3
     0.6
     0.7
     0.8
      1

我的目标是使用我的数据集创建类似于(Dowen et al.，2012)报告的热点图.

My goal is to create a heatmap similar to the reported by (Dowen et al., 2012) using my dataset.

谢谢.

推荐答案

您可以使用image绘制单列数据集的热图:

You can plot a heatmap of a one-column dataset with image:

library(graphics)
mat <- matrix(c(-1, -1, -.9, -.8, -.2, .3, .6, .7, .8, 1))
image(mat)
