R - Ubuntu 上的闪亮服务器 [英] R - shiny server on Ubuntu

问题描述

我是 R、Shiny、Shiny Server 和 Ubuntu 12.04 的新手.经过漫长的一天，除了实际让闪亮的服务器托管我的应用程序之外，我几乎一切正常.我正在尝试在本地托管我的应用程序.

I'm fairly new to R, Shiny, Shiny Server and Ubuntu 12.04. After a long day I've got just about everything working except for actually having shiny-server host my app. I'm trying to host my app locally.

这是我的错误:

Error in library(ggplot2) : there is no package called ‘ggplot2’ Calls: runApp ...
startAppDir -> sys.source -> eval -> eval -> library 
Execution halted

这是>sessionInfo() 生成的一些相关信息:

我在没有 Shiny-server 的情况下进行了测试，该应用程序运行良好

I tested without shiny-server and the app works fine

runApp("/var/shiny-server/www/examples/MY_APP/")

我还测试了 Shiny-server 附带的示例，它们运行良好，但不使用 ggplot2.

I've also tested the examples that came with shiny-server and they work fine but they don't use ggplot2.

ggplot2 显然已安装，所以我怀疑这是权限问题(?)，但我不知道如何修复它...

ggplot2 is clearly installed so I suspect it's a permission issue (?) but I don't know how to fix it...

感谢您的帮助！

*解决方案*使用 .libPaths() 我能够确定由

*SOLUTION* Using .libPaths() I was able to determine that custom packages installed by

>install.packages("ggplot2")

放在主目录下

/home/USER/R/x86_64-pc-linux-gnu-library/3.0/ggplot2

我必须将文件夹~3.0/"中的每个文件都复制到

I had to copy every file from folder '~3.0/' into

/usr/local/lib/R/site-library

现在可以使用了！谢谢:D

It works now! Thanks :D

推荐答案

尝试将 ggplot2 包安装到系统目录(不是本地用户目录)，运行

Try installing ggplot2 package to the system directory (not local user directory), by running

sudo R
(within R session)
install.packages('ggplot2')

由于 shiny 可能以不同的用户名运行，因此它可能无法访问您本地安装的 R 库.

Since shiny may run under a different user name, it may not have access to your locally installed R libraries.
