R中的dist只能处理数据帧、向量、矩阵和列表
dist in R can only handle data frames, vectors, matrices, and lists
我正在尝试 运行 此代码从 UCR Time Series database 获取枪点数据集的层次聚类。但是我遇到了这个错误。有帮助吗？
library(dtw)
set.seed(6218)
n <- 10
sc <- read.table("/Users/mona/cs799/UCR_TS_Archive_2015/Gun_Point/Gun_Point_TRAIN")
s <- sample(1:100, n)
idx <- c(s, 100+s, 200+s, 300+s, 400+s, 500+s)
sample2 <- sc[idx, ]
distance.matrix <- dist(sample2, method="DTW")
hc <- hclust(distance.matrix, method="average")
plot(hc, labels=observedLabels, main="")
rect.hclust(hc, k=6)
memb <- cutree(hc, k=6)
table(observedLabels, memb)
这是错误：
Error in dist(sample2, method = "DTW") :
Can only handle data frames, vectors, matrices, and lists!
这是额外的信息：

您需要将 read.table 更改为：
sc <- read.table("~/cs799/UCR_TS_Archive_2015/Gun_Point/Gun_Point_TRAIN",
sep=",", stringsAsFactors=FALSE)
那么，您将至少拥有有效的数据来进行操作。
但是，sc 只有 50 行，idx 显然超出了某些值的行数（它生成了大量 NA）。
而且，如果其他人遇到此 post 和来自 UCR 时间序列分类档案（此处 http://www.cs.ucr.edu/~eamonn/time_series_data/UCR_TS_Archive_2015.zip）的此数据集，密码为 attempttoclassify。我害怕寻宝发现它并不像把它放在一起的学者所希望的那样可爱。
我正在尝试 运行 此代码从 UCR Time Series database 获取枪点数据集的层次聚类。但是我遇到了这个错误。有帮助吗？

您需要将 read.table 更改为：
sc <- read.table("~/cs799/UCR_TS_Archive_2015/Gun_Point/Gun_Point_TRAIN",
sep=",", stringsAsFactors=FALSE)
那么，您将至少拥有有效的数据来进行操作。
但是，sc 只有 50 行，idx 显然超出了某些值的行数（它生成了大量 NA）。
而且，如果其他人遇到此 post 和来自 UCR 时间序列分类档案（此处 http://www.cs.ucr.edu/~eamonn/time_series_data/UCR_TS_Archive_2015.zip）的此数据集，密码为 attempttoclassify。我害怕寻宝发现它并不像把它放在一起的学者所希望的那样可爱。
