[英]R heatmap.2 One row heatmap with color key
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). 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甲基化响应生物胁迫”中所述(Dowen等,2012)。 The following is a link to the article: pnas.org/content/109/32/E2183/1
以下是文章的链接:pnas.org/content/109/32/E2183/1
My effective data is just a column with values between -1 and 1: 我的有效数据只是一列,其值介于-1和1之间:
deltaMeth
-1
-1
-0.9
-0.8
-0.2
0.3
0.6
0.7
0.8
1
My goal is to create a heatmap similar to the reported by (Dowen et al., 2012) using my dataset. 我的目标是使用我的数据集创建类似于(Dowen et al。,2012)报告的热图。
Thanks. 谢谢。
You can plot a heatmap of a one-column dataset with image
: 您可以使用
image
绘制单列数据集的热图:
library(graphics)
mat <- matrix(c(-1, -1, -.9, -.8, -.2, .3, .6, .7, .8, 1))
image(mat)
