R: Installing package from Github on company network

Question

I would like to install and load this package from GitHub on my company laptop with a company network.

I have been facing issues with the two following possible solutions:

• When I download the zip and install it through RStudio>Tools>Install Packages>Install from: Package Archive File (.zip; tar.gz), it seems that the package is well installed. However, I have difficulties loading the package through library(photon-master). It tells me that package must be of length 1.

• When I try to install the package from GitHub, I also have some difficulties when I use the following code:

  require(devtools)  
  require(httr)
  set_config(use_proxy(url="userproxy.xxx.xxx.local", port=8080, username="IDxxxxxx",password="xxx"))
  devtools::install_github(repo = 'rCarto/photon')
  

  where the proxy server settings have been found in

Start>control panel>Network and Internet > click on Internet Options > click on connections tab then right at the bottom click on LAN settings > Check Proxy Server Settings

I get the following error message:

Error in curl::curl_fetch_disk(url, x$path, handle = handle) :
Failure when receiving data from the peer

Any solution would be greatly appreciated. I just want to use the package. Thanks in advance for your time
