Reading .data file in r

Question

I need to read a data file of type .data(can be found here ). I have never seen nor read a file like this before and when I try to read.table(file = "ionosphere.data") all of the attributes for a single instance are all grouped together. How do I properly read this file?

Answer 1

您只需要在read.table指定分隔符即可： read.table("https://archive.ics.uci.edu/ml/machine-learning-databases/ionosphere/ionosphere.data", sep = ",")

Answer 2

It's a UTF-16 file with a byte order mark at the beginning. read.table will fail unless you specify the correct encoding. This works for me on MacOS. Decimals are indicated by a comma.

read.table("ionosphere.data", fileEncoding="UTF-16", dec=",")

Answer 3

您可以下载文件并输入x<-read.csv("D:/filedestination/ionosphere.data",header=F)以查看数据view(ionosphere.data)
