R 导入 .data 文件扩展名

Question

您好，我正在尝试从 URL:https://archive.ics.uci.edu/ml/machine-learning-databases/housing/housing.data 导入数据，但它始终将其导入为单行。我用“\t”分割数据，但它仍然不起作用。我的 R 代码；

    bostonHousing <- read.table("https://archive.ics.uci.edu/ml/machine-learning-databases/housing/housing.data",
 col.names= c("CRIM","ZN","INDUS","CHAS","NOX","RM","AGE","DIS","RAD","TAX","PTRATIO","B","LSTAT","MEDV"),
                                  dec=",",sep = "\t")

Answer 1

该文件不是制表符分隔的，而是白色space 分隔的。默认情况下，read.table 假定列由一个或多个白色 space 字符分隔（制表符或 space）。仅当列以制表符分隔和数据列可能包含嵌入的 space 时，才真正需要指定制表符分隔符（或使用 read.delim()）...

url <- "https://archive.ics.uci.edu/ml/machine-learning-databases/housing/housing.data"
bostonHousing <- read.table(url)

似乎工作正常（dec="," 也是一个坏主意）
