R树状图故障中的热图功能 [英] Heatmap function in R dendrogram failure

问题描述

对于我的一生，我无法理解这种方法为何会失败，在此我非常感谢您多加关注:

For the life of me I cannot understand why this method is failing, I would really appreciate an additional set of eyes here:

heatmap.2(TEST,trace="none",density="none",scale="row", 
     ColSideColors=c("red","blue")[data.test.factors],
     col=redgreen,labRow="", 
     hclustfun=function(x) hclust(x,method="complete"),
     distfun=function(x) as.dist((1 - cor(x))/2))  

我得到的错误是: 行树状图排序给出了错误长度的索引

The error that I get is: row dendrogram ordering gave index of wrong length

如果我不包括distfun，则一切工作都很好，并且对hclust函数有响应.任何建议将不胜感激.

If I don't include the distfun, everything works really well and is responsive to the hclust function. Any advice would be greatly appreicated.

推荐答案

这还不能重现...

 TEST <- matrix(runif(100),nrow=10)
  heatmap.2(TEST, trace="none", density="none", 
            scale="row",
            labRow="",
            hclust=function(x) hclust(x,method="complete"),
            distfun=function(x) as.dist((1-cor(x))/2))

为我工作.我不知道redgreen或data.test.factors是什么.

works for me. I don't know what redgreen or data.test.factors are.

您是否尝试过使用debug(heatmap.2)或options(error=recover)(或traceback()，虽然不太可能单独使用)来跟踪错误的确切位置?

Have you tried debug(heatmap.2) or options(error=recover) (or traceback(), although it's unlikely to be useful on its own) to try to track down the precise location of the error?
