我正在使用gplots
并Rcolorbrewer
使用该heatmap2()
功能制作热图。
我的数据为零,表示此样本中没有记录任何数据。要创建热图,我希望将这些零着色为白色,其余部分在三色图例中。
这是到目前为止的代码:
my_palette <- colorRampPalette(c("blue", "green", "red"))(n = 299)
col_breaks = c(seq(0.001,0.2,length=100), seq(0.3,0.4,length=100), seq(0.5,0.6,length=100))
library(gplots)
heatmap.2(deco.hmBB, main = "BCC at day 0 and day 10", margins = c(6,9), trace = "none",
density.info = "none", dendrogram = "none", col = my_palette, breaks = col_breaks,
Colv = "NA")
