带有 R 的 sftp - sftp 不是带有 RCurl 的协议 [英] sftp with R - sftp not a protocol with RCurl

问题描述

我已经阅读了一些关于使用 R 的 sftp 的帖子，但无法解决我遇到的问题.有一个不错的变化，我只是没有在正确的地方搜索，如果是这样，请指出正确的方向.这是我所在的位置:

I've read a few posts on sftp with R, but was not able to address the problem that I have. There's a decent change I'm just not searching in the right place, and if that's the case, please point me in the right direction. Here's where I'm at:

> library(RCurl)
> curlVersion()
$age
[1] 3

$version
[1] "7.43.0"

$vesion_num

$host

马上，我注意到 sftp 不是我当前版本的 RCurl 接受的协议，这是我的主要问题.结果，当我运行下面的代码时，出现以下错误:

Right away, I notice that sftp is not a protocol accepted in my current version of RCurl, which is my main problem. As a result, when I run the following code below, I get the following error:

# Input 
protocol <- "sftp"
server <- "00.000.00.00"
userpwd <- "userid:userpass"
tsfrFilename <- 'myfile.txt'
ouptFilename <- 'myfile.txt'

# Run
url <- paste0(protocol, "://", server, tsfrFilename)
data <- getURL(url = url, userpwd = userpwd)

Error in function (type, msg, asError = TRUE)  : 
  Protocol "sftp" not supported or disabled in libcurl

其实我还有第二个问题.我的理解是 getURL 从另一台服务器获取数据并将其拉到我的本地机器上，而我想将一个文件从我的本地机器上放到服务器上.

I actually have a second question as well. My understanding is that getURL grabs data from the other server and pulls it to my local machine, whereas I would like to put a file onto the server from my local machine.

总结:(1) 我可以更新 R 中的 RCurl/libcurl 以支持 sftp，以及 (2) 我如何将文件从本地机器放入服务器，而不是从服务器获取文件到我的本地机器?

To summarize: (1) can I update RCurl / libcurl in R to support sftp, and (2) how do i put files from my local machine into the server, rather than get files from the server to my local machine?

谢谢！
