Re: [R] escape character to get " printed in output
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"

Roger,
Don't use print(), use cat() so that the escaped characters are properly
interpreted:
> cat("hello \"hello\" hello\n")
hello "hello" hello

See ?cat

[R] escape character to get " printed in output
I want to use R to run dos commands (either by create batch files or
using shell())and I need to write double quotes on the file (or shell
command). As an easier example, lets take:
> print("hello 'hello' hello")
[1] "hello 'hello' hello"
Lets say instead of the above, I wanted:
"hello "hello" hello"
If possible, how would I do that?
I understand that \ is an escape character, so I tried:
> print("hello \"hello\" hello")
[1] "hello \"hello\" hello"
But that did not work.
TIA, Roger
