在Rstudio中我写道:
urlcoP <- "http://www.cophieu68.vn/datax123456/metastock_all_data.zip"
temp <- tempfile()
download.file(urlcoP,temp)
data <- read.table(unz(temp, "metastock_all_data.txt"))
但是它得到了错误:
Error in open.connection(file, "rt") : cannot open the connection
In addition: Warning message:
In open.connection(file, "rt") :
cannot locate file 'metastock_all_data.txt' in zip file 'C:\TEMP\RtmpaaH3PW\file135c1e97348'
原因是metastock_all_data.txt
位于zip中名为datax123456
的文件夹中。
答案 0 :(得分:2)
试试这个吗?
data <- read.table(unz(temp, "datax123456/metastock_all_data.txt"))
metastock_all_data.txt位于zip中名为datax123456的文件夹中,因此在metastock_all_data.txt之前添加文件夹
