使用 r 的异步网络 IO:任何现有包 [英] Asynchronous network IO using r: Any existing packages

问题描述

是否有任何促进异步网络 IO 的 R 项目包?我认为这里是 Ruby 的 Eventmachine 或 Python 的 Twisted.如果有几个这样的包/库在以下方面是最好的:- 表现- 功能

Are there any R-project packages that facilitate asynchronous network IO? I'm think here along the lines of Ruby's Eventmachine or Python's Twisted. If there are several such packages/libraries which is the best in terms of: - performance - features

推荐答案

首先，R 是单线程的，所以通常人们会尝试使用并行计算方法(例如，参见 snow 包).我不认为有任何东西像 Eventmachine 或 Twisted.

First of all, R is single-threaded, so typically people try to use parallel computing approaches (see, for instance, the snow package). I don't think there's anything quite like Eventmachine or Twisted.

查看以下内容:

• State of the Art in Parallel Computing with R"一文描述了 R 中的大多数并行计算方法(http://www.jstatsoft.org/v31/i01/paper).HighPerformanceComputing 视图中有许多有用的包:http://cran.r-project.org/web/views/HighPerformanceComputing.html.
• 查看 svSocket:http://cran.r-project.org/web/packages/svSocket/
• 您可以尝试将 NetWorkSpaces 与 R 一起使用:http://cran.r-project.org/web/packages/nws/.
• 有几个 R 服务器示例.RServe:http://www.rforge.net/Rserve/
• iBrokers 包是我所知道的唯一使用异步请求的包之一.查看该包的源代码(您可以从 R-Forge 下载它)和相关的小插图:http://cran.r-project.org/web/packages/IBrokers/vignettes/RealTime.pdf
• biocep 项目还包括许多相关功能:http://biocep-distrib.r-forge.r-project.org/

• The "State of the Art in Parallel Computing with R" paper describes most of the approaches to parallel computing in R (http://www.jstatsoft.org/v31/i01/paper). There are many useful packages in the HighPerformanceComputing view: http://cran.r-project.org/web/views/HighPerformanceComputing.html.
• Check out svSocket: http://cran.r-project.org/web/packages/svSocket/
• You can try using NetWorkSpaces with R: http://cran.r-project.org/web/packages/nws/.
• There are several examples of R servers. RServe: http://www.rforge.net/Rserve/
• The iBrokers packages is one of the only ones that I know which uses asynchonous requests. Have a look at the source code for that package (you can download it off R-Forge) and the related vignette: http://cran.r-project.org/web/packages/IBrokers/vignettes/RealTime.pdf
• The biocep project also includes many relevant features: http://biocep-distrib.r-forge.r-project.org/
