This post pertains to R proxy issues on  nix  You should know that R has many libraries methods to fetch data over internet   For  curl    libcurl    wget  etc  just do the following    Open a terminal  Type the following command   sudo gedit  etc R Renviron site  Enter the following lines   http proxy  http   username password abc com port   https proxy  https   username password xyz com port     Replace username  password  abc com  xyz com and port with these settings specific to your network  Quit R and launch again    This should solve your problem with  libcurl  and  curl  method  However  I have not tried it with  httr   One way to do that with  httr  only for that session is as follows   library httr  set config use proxy url  abc com  port 8080  username  username   password  password      You need to substitute settings specific to your n w in relevant fields

The problem is with your curl options  ndash  the RCurl package doesn t seem to use internet2 dll  You need to specify the port separately  and will probably need to give your user login details as network credentials  e g    opts  lt - list    proxy            999 999 999 999      proxyusername    mydomain  myusername      proxypassword    mypassword      proxyport       8080   getURL  http   stackoverflow com    opts   opts    Remember to escape any backslashes in your password   You may also need to wrap the URL in a call to curlEscape

For RStudio just you have to do this   Firstly  open RStudio like always  select from the top menu    Tools-Global Options-Packages  Uncheck the option  Use Internet Explorer library proxy for HTTP  And then close the Rstudio  furthermore you have to    Find the file   Renviron  in your computer  most probably you would find it here  C  Users your user name Documents  Note that if it does not exist you can creat it just by writing this command in RStudio   file edit     Renviron    Add these two lines to the initials of the file   options internet info   0   http proxy  http   user id password your proxy your port     And that s it

Inspired by all the responses related on the internet  finally I ve found the solution to correctly configure the Proxy for R and Rstudio    There are several steps to follow  perhaps some of the steps are useless  but the combination works    Add environment variables http proxy and https proxy with proxy details   variable name  http proxy variable value  https   user id password your proxy your port   variable name  https proxy variable value  https    user id password your proxy your port  If you start R from a desktop icon  you can add the --internet flag to the target line  right click -  Properties   e g  C  Program Files R R-2 8 1 bin Rgui exe  --internet2 For RStudio just you have to do this   Firstly  open RStudio like always  select from the top menu   Tools-Global Options-Packages  Uncheck the option  Use Internet Explorer library proxy for HTTP Find the file   Renviron  in your computer  most probably you would find it here  C  Users your user name Documents    Note that  if it does not exist you can create it just by writing this command in R   file edit     Renviron     Then add these six lines to the initials of the file   options internet info   0   http proxy   https    user id password your proxy your port  http proxy user   user id password  https proxy   https    user id password0 your proxy your port  https proxy user   user id password  ftp proxy   user id password your proxy your port  Restart R  Type the following commands in R to assure that the configuration above works well   Sys getenv  http proxy    Sys getenv  http proxy user    Sys getenv  https proxy    Sys getenv  https proxy user    Sys getenv  ftp proxy    Now you can install the packages as you want by using the command like   install packages  mlr  method  libcurl     It s important to add method  libcurl   otherwise it won t work

Tried all of these and also the solutions using netsh  winhttp etc  Geek On Acid s answer helped me download packages from the server but none of these solutions worked for using the package I wanted to run  twitteR package    The best solution is to use a software that let s you configure system-wide proxy   FreeCap  free  and Proxifier  trial  worked perfectly for me at my company   Please note that you need to remove proxy settings from your browser and any other apps that you have configured to use proxy as these tools provide system-wide proxy for all network traffic from your computer
