Question

我要绘制一个相关数据的热图,而不是从0.85获得相关比例尺,我要的是0.90。我要知道如何调整这个比例尺。

我使用的命令是:

data<-read.table("data_corr", header=T) 
tiff( corrheatmap.tiff )
library(gplots)
z<-cor(data)
lowColor = "purple" #change this if you want
highColor = "blue" #change this if you want
colorMin = 0 # I have made this 0.9 and also 90 in any case I don t see the difference
heatmap.2(z, Rowv=FALSE, Colv=FALSE, dendrogram="none", key=TRUE, density.info="none", trace="none", col=colorpanel(100, lowColor, highColor), scale="none", cexRow=0.15, cexCol=0.15)

或许我误解了你的问题但我认为你可以用断断断续续的争论

heatmap.2(z, breaks = seq(0.9, 1, 0.001), Rowv=FALSE, Colv=FALSE, dendrogram="none", key=TRUE, density.info="none", cexRow = 0.15, cexCol = 0.15, col=colorpanel(100, lowColor, highColor), trace="none")
