Rpad and R 2.10.0
I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7,
browser is Firefox)
Just starting Rpad by
library(Rpad)
Rpad()
opens the browser and displays the
.html files and the .Rpad files in my home directory, but these
files do not have links and are not clickable.
Doing the same in R 2.9.2 gives clickable links in the browser.
Furthermore, in both cases an empty graphics window

and I need to count the number of cells containing a count of 1 for each
of the factors values defining the first dimension.
Here is my attempt:
tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM))
tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0))

Computing tab2 is very slow.
Is there a faster

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

Hi, this is Charlie. I have installed the Rpad on my server (using Fedora
Core 6 with httpd2.24-2, mod_perl 2.0.2-6.1, perl 5.8.8 from RPM). When I
access to the Rpad (through http://localhost/Rpad/basehtml), it shows me the
main page as normal, however, problems occurs when I am testing the
examples. It shows me a long message like:

Having a go at Rpad
Context: FreeBSD 6.1on a pentium 4; apache 2 server up & running; mod_perl

Willing to use Rpad on an office intranet, I installed the Rpad package

HTML masked (due to Rpad?)
With an older verion of R (I think 2.2.0) and an older version of Rpad I
used to use HTML(go, collapse=false) where go is list of objects returned by
a function and this worked great. Now that I have done some upgrading (to R
2.3.1 and Rpad 1.1.0) its not working right. I also get a warning when I
start R that HTML is masked. And when I do ?HTML R tells me that HTML shows

still having trouble executing a Rpad website properly.

How to install the server version of rpad
Hi,
How can I install the server version of rpad on a website. I have read
the instructions in http://www.rpad.org/Rpad/ServerNotes.html, but
could not figure out how. Do I have to have something like Apache on
the website? Is there any instructions in addition to those on
http://www.rpad.org/Rpad/.
Thanks,

source and textConnection
Is this warning given on purpose?
> myconn<-textConnection("print(11*11)")
> source(myconn)
[1] 121
Warning message:
In source(myconn) : argument 'encoding = "native.enc"' will be ignored
Could it be omitted, since the docs state that encoding is only use if
the corresponding argument is a file name or url?

Excel
A common process when data is obtained in an Excel spreadsheet is to save
the spreadsheet as a .csv file then read it into R. Experienced users
might have learned to be wary of dates (as I have) but possibly have not
experienced what just happened to me. I thought I might just share it with
r-help as a cautionary tale.
I received an Excel file giving patient details. Each patient had an ID

bivariate weighted kernel density estimator
Is there code for bivariate kernel density estimation?
For bivariate kernels there is
kde2d in MASS
kde2d.g in GRASS
KernSur in GenKern
(list probably incomplete)
but none of them seems to accept a weight parameter
(like density does since R 2.2.0)

Forwarded to R-Help, because I think it could interest people following
this thread. Clearly, RServe and svSocket have different goals and very
little overlap.

Rpad graphics
I'm not sure this is the appropriate forum--please let me know if I
should post somewhere else.
I have Rpad version 1.3.0 set up on my webserver. It works, except
that graphics are not displayed. They are created (i.e., when I run
the example I see that graphics files are created in
Rpad/server/xxxxxxxxx) but they don't appear on the web page.
Everything else seems to be working. Any help
