Question

您好我正在尝试从网址导入数据：https://archive.ics.uci.edu/ml/machine-learning-databases/housing/housing.data但它始终将其作为单行导入。我将数据拆分为“\ t”，但它仍无法正常工作。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

文件没有标签分隔，它是以空格分隔的。默认情况下，read.table假定列由一个或多个空白字符（tab 或空格）分隔。当列以制表符分隔和时，指定制表符分隔符（或使用read.delim()）才真正有必要，数据列可能包含嵌入的空格......

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）

R import .data文件扩展
