R Reading in a zip data file without unzipping it

Question

I have a very large zip file and i am trying to read it into R without unzipping it like so:

temp <- tempfile(\"Sales\", fileext=c(\"zip\"))
data <- re         


        

Answer 1

If your zip file is called Sales.zip and contains only a file called Sales.dat, I think you can simply do the following (assuming the file is in your working directory):

data <- read.table(unz("Sales.zip", "Sales.dat"), nrows=10, header=T, quote="\"", sep=",")
