Re: [R-SIG-Mac] Download data from Internet contained in a Zip file

[Christofer Bogaso]

Hi David,

Above problem to my system appears like due to use of older R version.
I have secured a new Mac from my friend, rerun your suggestions with R
version 3.3.2 (2016-10-31)

Your instruction works perfectly fine there. Thanks,

 When I try to access the link

 manually, then download the zip file and then unzip it, I get a file

 the data.

 I was just trying to perform similar task, however through R, so that
 I can load data automatically directly from Web.

 Any Idea please. I am using below version of R (I know this is quite
 old version, however I am not currently in a position to upgrade my
 Macbook)

[Christofer Bogaso]

Thanks David for your detailing. However still it not working for me :

Do I need to install something to get it worked?

However,

as a workaround can you please suggest if below data can be downloaded
directly into R? Since my only expectation is to get Data
automatically, if below works then I can still happily live with that

I didn't try to use R to unzip it. Just using my system facilities worked fine.

Hi David et al,

Thanks for showing the pointers. With your approach, I see the
"temp.zip" file in my working folder.

However still I could not extract the data within it. I tried using
unzip() function, however not really going through :

Warning message:

When I try to access the link

manually, then download the zip file and then unzip it, I get a file
called "NAV_File_23122016.out". Which next I open in excel and get all
the data.

I generally use the downloader package. It sets up the call to download.file so 
that it succeeds with https URLs.

Re: [R-SIG-Mac] Download data from Internet contained in a Zip file

[Gábor Csárdi]

Your R build does not support HTTPS.

I suggest that you use the curl package if you can. HTTP support in
base R is very limited currently.

[R-SIG-Mac] Download data from Internet contained in a Zip file

[Christofer Bogaso]

Hi again,

I posted this in general R thread, however it is suggested this group
since I am using MAC OS 10.7.5.

I was following the instruction available in
"http://stackoverflow.com/questions/3053833/using-r-to-download-zipped-data-file-extract-and-import-data;
to download data from Internet contained in a zip file from the
address :

https://npscra.nsdl.co.in/download.php?path=download/=NAV_File_23122016.zip

However when I tried to follow the instruction I am facing below error :

> temp <- tempfile()
> download.file("https://npscra.nsdl.co.in/download.php?path=download/=NAV_File_23122016.zip",temp)
Error in 
download.file("https://npscra.nsdl.co.in/download.php?path=download/=NAV_File_23122016.zip;,
 :
  unsupported URL scheme

Can someone here please tell me what went wrong in above?

Highly appreciate your feedback.

Thanks for your time.
