Does the current R session support ANSI colors?
has_color()
The following algorithm is used to detect ANSI support:
If the crayon.enabled option is set to TRUE
with options(), then TRUE is returned. If it is
set to something else than TRUE (typically FALSE),
then FALSE is returned.
Otherwise, if the standard output is not a terminal, then
FALSE is returned.
Otherwise, if the platform is Windows, TRUE is returned
if running in ConEmu (https://conemu.github.io/) or
cmder (http://cmder.net) with ANSI color support.
Otherwise FALSE is returned.
Otherwise, if the COLORTERM environment variable is
set, TRUE is returned.
Otherwise, if the TERM environment variable starts
with screen, xterm or vt100, or matches
color, ansi, cygwin or linux
(with case insentive matching), then TRUE is returned.
Otherwise FALSE is returned.
TRUE if the current R session supports color.
