Question in Using sink function
Could anyone please explain to me why the following writes nothing into
"all.Rout"
file? If the "for" loop is removed, t.test output can be written into
"all.out".
Thanks in advance.

zz <- file("all.Rout", open="wt")

Cy3<-X[,2*i-1];

sink() does not seem to release the file

Problem with sink() in 1.20 on Windows (PR#779)
When I use sink(filename) to save the results of the run, the file
does not seem to be closed or released back to the OS after I issue
the "sink()" command. Here is a baby example:
sink("test.txt")
tdta <- data.frame(x = x <- 0:10,y = 2 * x + rnorm(11))
print(summary(lm(y ~ x, data=tdta)))
sink()
At this point (even after refreshing the Explorer window) the filesize

Ideas needed on automation of R
I need some guidance on what is the best way to automate R I am aware of
Rterm.
First question: Is it true that R is not currently OLE accessible under
Windows 2000?
Second question: Is there an R command that echoes all R Console results to
a run log system file?
My first attempt to write a run log file is the example from the R Data
Inport/Export documentation.

Add "title" in sink output and possibility of plot-like output for text
Hello,
I have been using sink to create text file outputs.
>sink("summ_model1and2.txt")
> summary(model1)
> summary(model2)
> sink()
Q1: Is there a way I could add a line of the text above the summary to act
like a title?
Also, I have been using the following to save plots from the lm function:

SUGGESTION: Option to have menu() and select.list() to use stderr (or even "prompt" output)
SEND TO STDERR:
Currently utils::menu() and utils::select.list() with graphics=FALSE
queries the user via the standard output (stdout). I'd like to
suggest to do this via standard error (stderr) instead, or at least
have an option to choose which output stream.
If they would send to stderr, they could also be used in various
report generators that capture stdout and redirect to the generated

sink behavior
There is a package called 'safe' that produces an object which I can
only write to a file using the sink() function. It works fine if the
sink() command is not inside of a function, but it does not write
anything to the file if the command is within a function.
Sample code:
# Using a matrix because as a simple example.
dumpMatrix = function(mat) {
sink(file = "mat.txt")

Sink for a subdirectory
Hi, how do I sink output to a subdirectory under which R is running?
For example, suppose R is running in ~me and I would like to sink output to
~me/Subdir/filename.
The obvious sink( "Subdir/filename" ) does not seem to work.
Thanks very much.

using the sink() function in a for-look
hi all,
i wanted to use the sink function to sequentially output regression
summaries within a for-loop. i must have something wrong somewhere (or be
using the sink function incorrectly), but can anyone help?
the code I am using is:
where data.x is a data.frame of independents, and data.y is a data.frame of
dependents.

sink() & windows printing
I used sink() a lot under linux with no problems.
Under windows 2000 & using R 1.5.1, I do the following:
- use sink() to direct ouput to a file
- use sink() again to direct output to screen
- print the file (to a network printer)
PROBLEM: the file stays spooled infinitely at the printer. Sometimes the
spooling gets translated into a printer error. The only way to get any
printing working

Any suggestions?

I have the same question that Eusebio had:
Is there a function similar to "sink" that redirect also R code to a
file that
is:

A <- matrix(x, ncol=3)

Error : sink stack is full
Hello,
I have implemented a method which uses sink to follow the progression status
of an iterative process (Below is part of the code)
I have already used such kind of code with no problem. Today, I get a "sink
stack is full" error.
I wonder if it could be linked with the fact that my .RData has a large size
(around 7 Mo) ???
I hope that someone can help me ...
Thanks in advance
