[R] How to use escape characters in a string

[Bert Gunter]

Please read R FAQ 7.37.

You need to escape the backslash:
> z<- as.character("`X^`R\\`S")
> z
[1] "`X^`R\\`S"
> cat(z)
`X^`R\`S

Subject: [R] How to use escape characters in a string

Hi,
I want to use a character as below in R,

 as.character("`X^`R\`S")
[1] "`X^`R`S"
Warning messages:
1: '\`' is an unrecognized escape in a character string
2: unrecognized escape removed from "`X^`R\`S"

But I found errors.
Can I use some option in as.character() to change this?

Thanks

Mary
