plotly installation with R

i want to install plotly package in R, from github

library(devtools)
install_github("ropensci/plotly")

and i have an error message:

Downloading github repo ropensci/plotly@master
Error in function (type, msg, asError = TRUE)  : couldn't connect to host

i have searched on the internet and i found that it's a problem of proxy, i tried:

set_config(
use_proxy(url="https://github.com/ropensci/plotly", port=8080, username="***",password="***")
)

but still have the same problem, i don't know what to put in url and port values, i have two accounts on Githup and plotly

thank you for your help

It looks like you are in some special network that your network administrator restricts the access to the address (https://github.com/ropensci/plotly) though a different port (8080).

To set a proxy, please replace the target URL (https://github.com/ropensci/plotly) with the a proxy web address. Namely, change your code to:

set_config(use_proxy(url="proxy.aaa.com", port=8080)

Assuming this proxy.aaa.com is the proxy you can use, but this should not be your target address.

More information, can try ?use_proxy

It's only a proxy problem if your network (probably employer) uses a proxy server on their perimeter.

If it really is a proxy, problem you'll have to use a different method to set the proxy for plotly operations, since it uses curlPerform from RCurl directly. Something like this:

opts <- list(
  proxy         = "YOUR_PROXY_HTTP_URL",
  proxyusername = "YOUR_PROXY_USERNAME", 
  proxypassword = "YOUR_PROXY_PASSWORD", 
  proxyport     = YOUR_PROXY_PORT
)

options(RCurlOptions = opts)

before you do any plotly operations.

You will need to use the values provided by your employer or network provider (i.e. not GitHub or plotly) for those values.
