R help - Apr 2011 - blank space escape sequence in R?

Is there a blank space escape sequence in R, i.e. something like \sp etc. to
produce a blank space?

TIA

You need to give some context.  A blank in a character vector will be 
printed as a blank, so you are probably talking about something else, 
but what?

Is it possible to use \x20 or some similar way to evoke the hexadecimal 
ascii form of blank?  That works in perl as does \040 for the octal form.

You can embed hex escapes in strings (except \x00). The value(s) that
you embed will depend on the character encoding used on you platform. If
this is UTF-8, or some other ASCII compatible encoding, \x20 will work:

[1] "foo bar"

For other locales, you might try charToRaw(" ") to see the binary
(hex)
representation for the space character on your platform, and substitute
this sequence instead.
