Does not work when proxy is used to connect to the internet

[rfhb]

Main functions in the package use internet connections for retrieval of trial information over the internet. These functions do not work and raise a time out error if internet connections have to use a proxy. This is usually the case in corporate environments. Better support for automated detection and handling should be included in the ctrdata package (which uses package curl, which has functions for handling proxies but does not do this automatically).

[rfhb]

A temporary remedy for simple proxies (no authentication) is to execute these commands before using package ctrdata:

# set proxy
Sys.setenv(http_proxy = curl::ie_get_proxy_for_url())
Sys.setenv(https_proxy = curl::ie_get_proxy_for_url())
