R help - May 2010 - Getting sink to work with “message” on R 2.11.0 - what did I miss?

Hi all,

I am trying to use type message with sink, like this:

sink("all.Rout", type="message")
1+3

sink()

readLines(con = "all.Rout")

So to get the following output:
> 1+3
[1] 4

Obviously this doesn't work.

I tried some variations (based on the explanations in the help) but am
missing something on how to make it work.

Any suggestions?

(p.s: I need this so to help Faiz Rasool in his latest post)

Thanks,

Tal

What are you trying to do? The sink help page has two rather dire  
warnings about not using type="message",  and using type="output
would
give you what you ask:

 > sink("all.Rout", type="output")
 > 1+3
 >
 > sink()
 >
 > readLines(con = "all.Rout")
[1] "[1] 4"

The extra "[1]" and quotes are from the readLines function, not from  
all.Rout.

I probably shouldn't be replying, as I believe this may require system
specific tricks that I don't know. To that end, you should probably provide
the minimum required information (e.g. from sessionInfo() + any other
OS/shell info) requested by the posting guide.

AFAIK, this can't be done in R. The history mechanism -- ?history --
(details of which are system dependent) records typed commands.  sink()
records output. The twain don't meet.
