r install.packages to install downloaded packages -

-

I am trying to install and update the packages install.packages (ask = wrong) downloads packages but If there is an error, it stops, if I run it again, it downloads the package again.

I am using Debian stable Linux with Backport repositories, as explained earlier:

This answer is for a Linux system, though I think the windows should not be different. When you try to install a package, at the end of the process (whether successful or not), tells you where to download the package you should see something like this: 

  # Downloaded source packages # â ???? / Tmp / rtmpSPFiKl / download_packagesâ ????   
 The path can change on a case basis. Store the source packages in a temporary folder; This means that the next time you reboot, the files will disappear. So, suppose I was trying to install a package for which some system requirements are necessary. I get an error then I proceed to install the required system packages. When I try to set R package back, I can:  
  install.packages ("/ tmp / rtmpSPfiKl / download_packages / packagename.tar.gz", repos = NULL)   
 Do not download it for the second time.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
