export tables to Excel files
Dear R users,
I've just posted a similar question about Illustrator.
This time I would like to export the results of my statistic tables and
my dataframes into Excel files.
Up to now I've used write.csv(), but I have to resave every file in .xls
in Excel.
I would like to know if there is a function or package to export
directly into *.xls.
I have found xlsReadWrite which would be

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

Windows 7, update.packages problem: "unable to move temporary installation"?
Hello all,
I am using R 2.13.0 with windows 7, after giving my user full privileges to
the R folder (as described
here<http://www.r-statistics.com/2011/04/how-to-upgrade-r-on-windows-7/>
).
This allows me to install new packages just fine.
However, when using update.packages(), to update existing packages, I keep
getting the following error (for example, when updating the MASS package):

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,

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"

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

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])

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?

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?

Extracting the terms from an rpart object
Hello all,
I wish to extract the terms from an rpart object.
Specifically, I would like to be able to know what is the response variable
(so I could do some manipulation on it).
But in general, such a method for rpart will also need to handle a "." case
(see fit2)
Here are two simple examples:
fit1 <- rpart(Kyphosis ~ Age + Number + Start, data=kyphosis)
