Might someone advice me about the following question:

Adding a "description" meta-tag to the R homepage (bump)
Hello dear R-devel,
I am allowing myself to bump this issue again (half a year later) -
I think that the www.r-project.org website could benefit from having a
description meta-tag.
Could anyone please let me know who to contact regarding this?
With much respect,

Capturing R console output into a file (sink+savehistory ??)
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
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

Hello dear R-help mailing list.
I wish to be able to have htmlParse work well with Hebrew, but it keeps to
scramble the Hebrew text in pages I feed into it.
For example:

u = "http://humus101.com/?p=2737"
a = getURL(u)

Why am I getting different results from cor VS ccf ?
Hi all,
I am getting different results from ccf and cor,
Here is a simple example:
set.seed(100)
N <- 100
x1 <- sample(N)
x2 <- x1 + rnorm(N,0,5)
ccf(x1,x2)$acf[ccf(x1,x2)$lag == -1]
cor(x1[-N], x2[-1])
Results:
> ccf(x1,x2)$acf[ccf(x1,x2)$lag == -1]
[1] -0.128027
> cor(x1[-N], x2[-1])

It seems that the "index.html" pages on CRAN are gone.
For example:

Who should this be forwarded to?

Why doesn't my change of "Renviron.site" work on "windows 7" ?
Hi all,
I added the following line on the "Renviron.site" file:

And when I start R and run:
.libPaths()
I don't see this path.
On windows XP it worked for me. I am now using windoes 7 (64 bit) with R

Is there a reason this shouldn't work?
