unzip a .zip file

Question

I want to unzip a file in R. I completely don't know what to do.

I searched and I found it method like this :

unzip(zipfile, files = NULL, list = FALSE, overwrite = TRUE,       junkpaths = FALSE, exdir = ".", unzip = "internal",       setTimes = FALSE) 

but I don't know what should I do with this.

Answer 1

You could do it like this:

zipF<-file.choose() # lets you choose a file and save its file path in R (at least for windows) outDir<-"C:\\Users\\Name\\Documents\\unzipfolder" # Define the folder where the zip file should be unzipped to  unzip(zipF,exdir=outDir)  # unzip your file  

Well you could also define both paths in R the classical way:

Assuming your zip file is named file.zip

zipF<- "C:\\path\\to\\my\\zipfile\\file.zip" outDir<-"C:\\Users\\Name\\Documents\\unzipfolder" unzip(zipF,exdir=outDir) 

exdir defines the directory to extract files to. It will be created if not already available. If you don't set exdir, unzip will just unzip it to your current working directory.
