Fixing “Peer certificate cannot be authenticated”

I’m currently getting the following error on a Windows machine:

> devtools::install_github("hadley/readr")
Error in curl::curl_fetch_disk(url, x$path, handle = handle) : 
  Peer certificate cannot be authenticated with given CA certificates

The machine in question is sitting behind a gnarly firewall and proxy, which I suspect are the source of the problem. I also need to use --ignore-certificate-errors when running chromium-browser, which points to the same issue.

This seems to resolve the issue:

> library(httr)
> set_config(config(ssl_verifypeer = 0L))
