[R] Getting sink to work with "message" on R 2.11.0 - what did I miss?

[Bert Gunter]

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.

Subject: [R] Getting sink to work with "message" on R 2.11.0 - what did I

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
