This returns me with:

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])
[1] -0.1301427

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

Is it possible to "right align" text in R graphics?
Hello all,
The following line of code includes a right-to-left language text, yet the
R graphics engine displays it from left to right. One problem this causes
is when there are parenthesis in the test, here is a basic example?
plot(1:10, main = "שלום (טקסט)")
Is there a way to make sure the text is displayed from right to left?
Many thanks for any suggestions,

Combining several plots besides a dendrogram?
Hello all,
I would like to recreate the plot shown here (from a useR 2009
presentation):
http://www.agrocampus-ouest.fr/math/useR-2009/abstracts/pdf/Hocking.pdf
I downloaded the code for that image, and discovered that it relies on
external web services, and also having PERL installed on the computer.
I believe this could be done "locally" using the "seqLogo"

Is there a way to have 'comment' keep a list?
Hello all,
I recently discovered the "comment" command.
I see it can only hold a vector of characters.
Is there a way (or an alternative), to make it possible to have it keep a
list?
(for example, to keep different pieces of information like date of creation,
information of each variable and so on)
The closest solution I can think of is using 'names' on the vector, like
this:

Is there an implementation for "URL Encoding" (/format) in R?
Hello all,
I would like some R function that can translate a string to a "URL encoding"

Is it implemented? (I wasn't able to find any reference to it)

Where can I find a working libeay32.dll file for RCurl ?
Hi all,
I was trying to run the latest version of RCurl on windows 7 with R 2.12 and
got a "missing libeay32.dll" error.

And placed it in the system32 folder.
Now I get the following error:

Unexplained behavior of level names when using ordered factors in lm?

I am unable to understand why when I run the following three lines:
set.seed(4254)

> summary(lm(y ~ x, a))
The output I get includes factor levels which are not relevant to what I am
actually using:
Call:

The CRAN packages webpages are not found
I am not sure who to send this to - so I am writing this here.
It seems that the "index.html" pages on CRAN are gone.
For example:
http://cran.r-project.org/web/packages/ggplot2/index.html
Is gone. But the directory is accessible:
http://cran.r-project.org/web/packages/ggplot2/
Who should this be forwarded to?

Consistency of variable storage in R and Sys.setlocale (is this a feature or bug)?

Hello dear R-devel members,
I came by an oddity, with regards to how character variables are being
transformed when they are in Hebrew, and when Sys.setlocale is changed.

Why doesn't my change of "Renviron.site" work on "windows 7" ?
Hi all,
I added the following line on the "Renviron.site" file:
R_LIBS=C:\Program Files (x86)\R\library
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
32.
Is there a reason this shouldn't work?

Why is vector assignment in R recreates the entire vector ?
Hello all,
A friend recently brought to my attention that vector assignment actually
recreates the entire vector on which the assignment is performed.
So for example, the code:
x[10]<- NA # The original call (short version)
Is really doing this:
x<- replace(x, list=10, values=NA) # The original call (long version)
# assigning a whole new vector to x
Which is actually doing this:
x<-
