Internet Exists query — internetExists • Require

Simple test for internet availability.

Usage

internetExists(verbose = getOption("Require.verbose"), force = FALSE)

verbose: Numeric or logical indicating how verbose should the function be. If -1 or -2, then as little verbosity as possible. If 0 or FALSE, then minimal outputs; if 1 or TRUE, more outputs; 2 even more. NOTE: in Require function, when verbose >= 2, also returns details as if returnDetails = TRUE (for backwards compatibility).
force: If TRUE, probe even when options("Require.checkInternet") is FALSE. Used at points where we're about to do real work (e.g., install dispatch) and a 2-second probe is cheap relative to the cost of failing late. Defaults to FALSE to preserve the no-probe default behaviour for all other call sites.

Logical. TRUE if internet is available, FALSE if not.
