如何在网页上设置基于 R 的服务 [英] How to set up an R based service on a web page

问题描述

我想在网页上提供以下服务:

I would like to provide the following service on a webpage:

• 每天运行一个 R 脚本来收集公开可用的数据并进行一些计算(我已经开发了该脚本，它需要一些额外的库！)
• 在网页上发布更新的图形和数字/文本输出

我不想一直运行自己的电脑，所以应该采用一种云解决方案(我猜?！?).

I don't want to run my own computer all the time so a kind of a cloud solution should be employed (I guess?!?).

您对如何实现上述想法有什么想法吗?

Do you have any ideas how to accomplish the above ideas?

推荐答案

您可以查看 FastRWeb - 它为 R 脚本提供服务如果它们是网页并且支持图形以及常规输出.它使用 Rserve，这使它比任何涉及启动 R 的解决方案(例如 R 或 Rscript)快得多.它可以通过 CGI 或 PHP 在任何网络服务器上运行.

You may have a look at FastRWeb - it serves R scripts as if they were web pages and supports graphics as well as regular output. It uses Rserve which makes it much faster than any solution that involves starting R (such as R or Rscript). It works on any webserver wither via CGI or PHP.

生成绘图的脚本如下所示:

A script to generate a plot would look like:

run <- function(n=100, ...) {
   p <- WebPlot(800, 600)
   n <- as.integer(n)
   plot(rnorm(n), rnorm(n), col=2, pch=19)
   p
}

其他解决方案是 RApache，它将 R 直接嵌入到 apache 网络服务器中.

Other solution is RApache which embeds R directly into the apache webserver.

还有 Jeff 现在Rook使用嵌入式 R HTTP 服务器(感谢 Joshua 指出这一点).

And also by Jeff there is now Rook that uses the embedded R HTTP server (thanks to Joshua for pointing that one out).

您提到每天运行 - 如果您不需要在线分析，您可以简单地使用 R 生成 html 页面和 png 文件并将它们发送到您的网络服务器 -全部在一个自动化脚本中.有很多 R 包可以促进 HTML 输出 - 只需在 CRAN 包列表中搜索 HTML.

You mentioned running it daily - if you don't need online analysis, you can simply generate html pages and png files with R and send them to your webserver - all in an automated script. There are many R package that facilitate HTML output - just search in the CRAN package list for HTML.
