R STDOUT is parsed and numbers, negative numbers, dates in the standard
format, strings, and R constants are identified and wrapped by special ANSI
scape codes that are interpreted by terminal emulators as commands to colorize
the output.  R STDERR is also parsed to identify the expressions warning and
error and their translations to many languages.  If these expressions are
found, the output is colorized accordingly; otherwise, it is colorized as
STDERROR (blue, by default).

You can customize the colors according to your taste, guided by the color
table made by the command @code{show256Colors()}.  You can also set the colors
to any arbitrary string.  In this case, it is up to you to set valid values.")
