r-如何在image.plot中编辑x轴上的元素 [英] r- how to edit elements on x axis in image.plot
问题描述
我为这些数据创建了一个图像图:
I have created a image plot for this data:
sample
p p.1 p.2 p.3 p.4
p 1.0000000 0.24077171 -0.66666667 -0.49009803 0.61237244
p.1 0.2407717 1.00000000 0.09028939 -0.83444087 0.14744196
p.2 -0.6666667 0.09028939 1.00000000 0.21004201 0.10206207
p.3 -0.4900980 -0.83444087 0.21004201 1.00000000 -0.08574929
p.4 0.6123724 0.14744196 0.10206207 -0.08574929 1.00000000
使用此代码:
image.plot(sample,col=redblue(191), zlim=c(-1,1))
我得到这张图片:
I get this image:
在x和y轴上代替0.0 0.2 0.4 ..我想要p p.1 p.2 ...
我如何得到那个?
感谢您的时间和考虑?
Instead of 0.0 0.2 0.4.. on x and y axes, I want p p.1 p.2... How do I get that that? Thank you for your time and consideration?
我的热图如下所示:
它不对称。你能解决这个问题吗?
我使用的是以下代码:
its not symmetric. Can you please fix this? I am using this code:
shades = c(seq(-1,-0.5,length = 64),seq (-0.5,0.5,长度= 64),seq(0.5,1,长度= 64))
heatmap.2(样本,树形图='无',symm = TRUE,Rowv = FALSE,Colv = FALSE,key = TRUE,cexCol = 0.7,cexRow = 1,scale =row,keysize = 1,col = redblue(191),break = shades)
shades=c(seq(-1,-0.5,length=64), seq(-0.5,0.5, length=64), seq(0.5,1,length=64))
heatmap.2(sample, dendrogram='none', symm=TRUE, Rowv=FALSE, Colv=FALSE, key=TRUE, cexCol=0.7, cexRow=1,scale="row", keysize=1, col=redblue(191), breaks=shades)
推荐答案
这是一个更好的解决方案:
Here is a better-ish solution:
par(mar=c(5,4.5,4,7))
image(sample, col=rainbow(25), axes=F) #redblue() doesn't work on my computer.
axis(2)
axis(1, at=seq(0,0.8,0.2), labels=rownames(sample))
image.plot(sample, legend.only=T)
编辑:下面的情节是否与您要找的一样?
Does the plot below look like what you are looking for?
sample = cor(matrix(rnorm(400), nrow=20))
image(cor(matrix(rnorm(400), nrow=20)), axes=F)
mtext(text=c(paste("country",1:21)), side=2, line=0.3, at=seq(0,1,0.05), las=1, cex=0.8)
mtext(text=c(paste("country",1:21)), side=1, line=0.3, at=seq(0,1,0.05), las=2, cex=0.8)
image.plot(sample, legend.only=T)
