如何利用热图在R中绘制一张热图。3包-HowtodrawaheatmapinRusingheatmap.3package

I've seen a few sources to draw a heatmap in R using the standard heatmap and heatmap.2 packages, but I have yet to come across an example using the new heatmap.3 package. The only source I could find for this was https://www.biostars.org/p/18211/. However, even here, the author makes his own heatmap.3 package, not the standard heatmap.3 package from CRAN http://cran.r-project.org/web/packages/GMD/GMD.pdf. I tried figuring out how to make a heatmap with heatmap.3 from that CRAN documentation, but I didn't even know where to start. I immediately got lost in all the 50+ options. Can anyone get me started?

我已经见过一些利用标准的热图和热图绘制出R的热图。两个包，但是我还没有看到一个使用新的热图的例子。3包。我能找到的唯一来源是https://www.biostars.org/p/18211/。然而，即使在这里，作者也有自己的热图。3包，不是标准的热图。3包来自CRAN http://cran.r project.org/web/packages/gmd/gmd.pdf。我试着弄清楚如何用热图制作一张热图。从那个CRAN文件中，我甚至不知道从哪里开始。我立刻在50多个选项中迷失了。有人能让我开始吗?

My tab-delimited input file looks like this:

我的表分隔输入文件如下所示:

EntryA  EntryB  EntryC  EntryD  EntryE
John    48  31  57  55
Mary    88  11  89  78
Sarah   33  66  42  54

1 个解决方案

library(GMD)

dat<-data.frame(EntryA=as.numeric(c(48,88,33)), EntryB=as.numeric(c(31,11,66)), EntryC=as.numeric(c(57,89,42)), EntryD=as.numeric(c(55,78,54)))

rownames(dat)=c("John","Mary","Sarah") 

ndat<-as.matrix(dat)

heatmap.3(ndat, Rowv=FALSE, Colv=FALSE)
