I got some info from google on how to read gz file . So I downloaded a file called gdc_download_20191030_052506.304900.tar.gz from https://gdc.cancer.gov/

I am now reading the file in R using this code. 

> z1 <- gzcon(gzfile("D:/New folder/gdc_download_20191030_052506.304900.tar.gz"))
> z1
A connection with                                                                                                            
description "gzcon(D:/New folder/gdc_download_20191030_052506.304900.tar.gz)"
class       "gzcon"                                                                                         
mode        "rb"                                                                                            
text        "binary"                                                                                        
opened      "closed"                                                                                        
can read    "yes"                                                                                           
can write   "yes"

But after this I am not able to see the table here. I think we need to perform other operations as well. Please guide

    Does this answer your question? [unzip a tar.gz file?](https://stackoverflow.com/questions/7151145/unzip-a-tar-gz-file) – Wimpel Oct 30 '19 at 10:58
  • Thanks. But there is a initial issue. In those solutions, there are data link directly. But I do not have a data link. I have a website and in the website when I click on download button, the data is downloaded and store in my local drive. I am not able to find the link to the data. Please advice – Dev P Oct 30 '19 at 12:01
  • can't you use the local link/path to your .tar.gz file? – Wimpel Oct 30 '19 at 12:06
  • I tried. But not working for example ````fn1 <- "D:/New Folder/gdc_download_20191030_052506.304900.tar.gz"```` then ````download.file(fn1,destfile="tmp1.tar.gz")```` – Dev P Oct 30 '19 at 12:08
  • why would you want to download a file that is already on your system? – Wimpel Oct 30 '19 at 12:23
  • Oh. Yeah. Then How do I proceed? You can use the file ````gdc_download_20191030_052506.304900.tar.gz```` to try in your system – Dev P Oct 30 '19 at 12:26
