如何安装RSAP软件包-SAP connector for R

我的要求是使用R分析来自我公司SAP系统的数据。我在本地计算机上使用R v.3.2.4，并且能够通过SAPGUI登录SAP

我发现，要将R连接到SAP，您需要RSAP软件包，要安装它，您需要在本地计算机上安装SAP NetWeaver RFC SDK

我尝试了以下步骤，但仍坚持在R中安装RSAP（步骤12）

如果您能给我一些建议，我将不胜感激

步骤根据：

步骤根据：在上安装文件

下面是错误：

Downloading GitHub repo piersharding/RSAP@master from URL h t t p s ://api.github.com/repos/piersharding/RSAP/zipball/master    
Error in curl::curl_fetch_memory(url, handle = handle) : 
  Problem with the SSL CA cert (path? access rights?)    
In addition: Warning message:
Username parameter is deprecated. Please use piersharding/RSAP 

我尝试了安装文件中建议的另一件事：

12] In R execute:
install.packages("RSAP", repos=c("h t t p://piersharding.com/R"), type="source")

这一次，系统做了更多的工作，但仍然没有成功：

很抱歉没有帮助，但是

install\u github

命令传递了一些参数，这些参数期望事情发生在位置

C:\\nwrfcsdk\\include

和

\lib

。你们研究过这个吗？这是安装文件所说的，但也许你们是对的，我会看一看。我还怀疑RTools不能按预期工作，或者GitHub回购问题。但这只是猜测，需要一些启发；）尝试安装另一个软件包以检查Rtoolchain是否正常工作。说

devtools:：install\u github（“hadley/ggplot2”）

。实际上，它不起作用，因为我遇到了以下错误：

下载github repo hadley/ggplot2@master从URLhttps://api.github.com/repos/hadley/ggplot2/zipball/master curl:：curl\u fetch\u内存（url，handle=handle）中出错：SSL CA证书（路径？访问权限？）

这是否意味着这是一个问题？这可能是兼容性问题，或者只是将某些文件放在某个目录中？也许？很抱歉没有帮助，但是
