After reading more, I understand I didn't formulate my last question
correctly, so please allow me to rephrase:
What I am looking for is a way to save the R console session output.
That is, a command that would combine the results of using:
?sink # And
?savehistory
I think there's still some ambiguity in the question; I'll try to answer
a few versions.
Do you want to run R normally, then afterwards save the console log?
That depends on what front end you're using. In the Windows GUI, you
can do it with
Ctrl-A to select everything in the console, then menu items File | Save
to file..., or just Ctrl-C to copy, and then paste it into Word.
Similar operations would work on a Mac.
Do you want to run code in a way that writes it to a file without
displaying it to the screen? R CMD batch does that.
Do you want to run just a few commands like that? Then try
capture.output(source(stdin(), echo=TRUE))
This will accept commands from the console until it hits an EOF (Ctrl-Z
on Windows, I don't know on other systems, but Ctrl-D is a good guess)
and will return
the results in a character vector, which you could write to a file.
Do you want to run R normally with output on screen, but also logging
everything to a file? I don't know how to do that in the R GUI in
Windows, but there are probably command line tools that could do it.

My motivation for this is that doing it will allow someone who is a blind
user of R to be able to easily export his results to word so he could have
word read him the text.
I also imagine it might be useful for session login.
Thanks,

Hi David,
I want to get both the 4 and the "1+3" that created it.
I am trying to help someone else on the mailing list that is looking for a
way to "sink" the console into word, so he could have word read it to him
(he is blind).
I know how to do the second part, but the first part (using sink with the
commands, and not just the output), I am somehow missing...
Best,
Tal

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.
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 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
