RStudio 未在 Ubuntu 16.04 上加载 RevoScaleR [英] RStudio not loading RevoScaleR on Ubuntu 16.04

问题描述

长话短说:
调用 rxImport() 在终端 R 会话中工作正常，但在使用 RStudio 时失败，尽管使用相同的 R 安装.

Long story short:
Calling rxImport() works fine in a Terminal R session but fails when using RStudio, despite using the same installation of R.

设置:
我想在 Ubuntu 上使用 RevoScaleR 函数，如 rxImport(...).我通过包管理器安装了 RStudio 和 R.

Setup:
I'd like to use RevoScaleR functions like rxImport(...) on Ubuntu. I have an installation of RStudio and R done through package manager.

我已经按照说明安装了 MS Rclient 此处.一切似乎都正常，因为我可以在终端中运行:

I've installed MS Rclient following the instructions here. Everything seems to work as I can run in the terminal:

/opt/microsoft/rclient/3.4.3/bin/R$ ./R

> R.home()

Error in rxImport() : 'inData' must be specified.

因此该函数默认加载并可用.现在，我通过在 ~/.profile 末尾添加以下内容来告诉 RStudio 使用此 R 安装:

So the function is loaded and available by default. Now I tell the RStudio to use this installation of R by adding the following at the end of ~/.profile :

RSTUDIO_WHICH_R="/opt/microsoft/rclient/3.4.3/bin/R/R"

错误:
当我运行 rstudio 时，我在 IDE 中得到一个 R 控制台，说:

Error:
When I run rstudio I get a R console in the IDE saying:

> R.home()
[1] "/opt/microsoft/rclient/3.4.3/runtime/R"
> rxImport()
Error in rxImport() : could not find function "rxImport"

可能的原因
我发现一些线程有人抱怨 MS 软件包没有正确处理~ 和工作目录(即在远程服务器上)，但是 setwd() 不能解决我的问题.

Possible causes
I've found some threads with people complaining about MS packages not dealing properly with ~ and working directory (i.e. on a remote server), setwd() doesn't solve my issue, though.

您对如何让 RevoScaleR 与 RStudio 一起工作有任何想法吗?提前致谢.

Do you have any ideas on how to get RevoScaleR to work with RStudio? Thanks in advance.

An answer I got from Github: https://github.com/rstudio/rstudio/issues/2455#issuecomment-375327109

尝试设置

R_LIBS_SITE=/opt/microsoft/rclient/3.4.3/libraries/RServer

在

/opt/microsoft/rclient/3.4.3/runtime/R/etc/Renviron
