Hi

I just discovered \r and \t

--8<---------------cut here---------------start------------->8---
> cat(LETTERS, "\n")
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
>
--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------start------------->8---
> cat(LETTERS, "\r", letters, "\n")
 a b c d e f g h i j k l m n o p q r s t u v w x y z
>
>--8<---------------cut here---------------end--------------->8---

and
\a as alert
\b as backspace
\f as form-feed
\n as newline
\r as carriage-return
\t as tab
\v as vertical-tab

are there more of these escape sequences?

Especially, Can I position the cursor at a specific column? I would like
to do this to show progress in an analysis done with mclapply() on
multiple cores and, preferably, display each core (7) at a fixed
position in a line.

Thanks,

Rainer
