我有一个非常大的 zip 文件,我正在尝试将其读入 R 而不像这样解压缩:
temp <- tempfile("Sales", fileext=c("zip"))
data <- read.table(unz(temp, "Sales.dat"), nrows=10, header=T, quote="\"", sep=",")
Error in open.connection(file, "rt") : cannot open the connection
In addition: Warning message:
In open.connection(file, "rt") :
cannot open zip file 'C:\Users\xxx\AppData\Local\Temp\RtmpyAM9jH\Sales13041760345azip'
