如何解决错误：存储错误。mode(X)&lt；-&quot；Double&Quot；：&#39；List&#39；对象不能强制为类型&#39；Double&#39； [英] how to solve error : Error in storage.mode(x) <- "double" : 'list' object cannot be coerced to type 'double'

问题描述

您好，我正在尝试运行SOM和KMeans分析。 但是我解不出来，因为有一个错误代码。 storage.mode(X)<；-"；DOUBLE&QOOT；中出错：无法将‘LIST’对象强制为类型‘DOUBLE’

如何解决此问题？

cdata <- read.delim("Cluster.txt", stringsAsFactors=FALSE)
cdata.n <- scale(subset(cdata, select=-c(ID)))
som_model2 <- supersom(data = cdata.n, grid = somgrid(10, 10, "rectangular"))
k = 6
somClusters <- kmeans(som_model2$codes, centers = 6)

我想培养成6个群集。 请帮帮我

我使用此数据。 https://github.com/woosa7/R_DataAnalytics/blob/08ea98289f4def3c4f72d4c10d3767784b42619b/R_DataMining/data/Cluster.txt

推荐答案

尝试unlist：

somClusters <- kmeans(unlist(som_model2$codes), centers = 6)
somClusters

Cluster means:
