The issue is resolved. The issue was resolved when I set this option prior to install_github command.

Here is what worked for me:

library(httr)
with_config(use_proxy(...), install_github(...))

OR

library(httr)
set_config(use_proxy(url = "******", port = ****))
devtools::install_github("username/packagename")
