R help - Nov 2008 - how to input a string without quote

Hi there,

I hope to use a string as an input in my function, however, I don't want
to input the quotation mark. Is it possible?

Thanks in advance.

Yeah, well, laziness is the mother of  creativity :-) .
But seriously: I know far too many engineers who  plug madly away for 
hours/days on end, where I would just stop, take a breath, figure out a 
method or mini-algorithm, and get the job done quick and easy.  That's 
what R is for.

Thanks!

However,

[1] "12345"

[1] "-"   "123" "X"

I hope to get:
"012345"
"0-123-X"
