@code{foreach} is an idiom that allows for iterating over elements in a

particular is intended to be used for its return value, rather than for its
side effects.  In that sense, it is similar to the standard @code{lapply}
function, but doesn't require the evaluation of a function.  Using
@code{foreach} without side effects also facilitates executing the loop in
parallel.")

to many other literate programming languages, with RSP it is straightforward
to loop over mixtures of code and text sections, e.g.  in month-by-month
summaries.  RSP has also several preprocessing directives for incorporating
static and dynamic contents of external files (local or online) among other
things.  RSP is ideal for self-contained scientific reports and R package

    (description "@code{colorout} is an R package that colorizes R output when
running in terminal emulator.

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.")
