[R] escape character to get " printed in output

[Bos, Roger]

Gabor & Marc,

Yes, you are right.  Thanks for clarifying that for me.  I should have
tested it fully before hand.

Thanks,

Roger

It did work.  That's how print represents strings.

Try:

> cat("hello \"hello\" hello")
hello "hello" hello>
> strsplit("hello \"hello\" hello", "")[[1]]
 [1] "h"  "e"  "l"  "l"  "o"  " "  "\"" "h"  "e"  "l"  "l"  "o"  "\"" "
"  "h"
[16] "e"  "l"  "l"  "o"
