The hclust function is based on Fortran code contributed to STATLIB by F. Murtagh. 参考 Becker, R. A., Chambers, J. M. and Wilks, A. R. (1988). The New S Language. Wadsworth & Brooks/Cole. (S version.) Everitt, B. (1974). Cluster Analysis. London: Heinemann Educ. Books. ...

Since in this case you already know that there could be only three types of wheat you will choose the number of clusters to be k = 3, or as you can see in the dendrogram h = 3 you get three clusters. You will use R's cutree() function to cut the tree with hclust_avg as one...
针对您遇到的hclust函数中的错误error in hclust(d, method = method) : na/nan/inf in foreign function call (arg 6),这个问题通常是由于输入的距离矩阵d中存在NA(缺失值)、NaN(非数字值)或Inf(无穷大值)导致的。以下是根据您提供的提示,逐步解决问题的步骤和代码示例: 1. 检查d中是否存在NA/NaN/Inf值...

"inf")小。 相等比较时,float("+inf")与float("+inf")、float("inf")三者相等。即:
原因是数据中有标准差sd为0的行,做归一化时报错。pheatmap中做归一化采用的是scale方法: 因此如果要做scale,需要将这样的行去掉: test<-data[apply(data, 1,function(x) sd(x)!=0),]pheatmap(test,scale ="row") Ref: https://stackoverflow.com/questions/30350438/pheatmap-scale-row-giving-error-in-...
