| setInternet2 {utils} | R Documentation |
With the --internet2 startup option, or via environment variable R_WIN_INTERNET2 or by calling this function, R will make use of the ‘internet2.dll’ library for Internet access, which makes use of Internet Explorer functions. This allows specification of proxies, etc., in the “Internet Options” applet in “Control Panel”.
setInternet2(use = TRUE)
use |
Whether to use ‘internet2.dll’. If |
R does not load either ‘internet.dll’ or ‘internet2.dll’
until needed, so it is certainly safe to call this function before
making any calls that access the Internet
(e.g. download.file). If one of the DLLs has already
been loaded, this function will switch to the other one without
unloading the first one, so there is a potential resource leak.
The previous setting is returned, invisibly if use is not NA.
