Help with RExcel (running code)
Hello:
First, RExcel completely rocks! Hat tip to the development team.
However, I don't understand something very basic about it.
Suppose I put the following code in two cells and choose the Run Code option
plot(runif(20),runif(20))
text(.5,.5,"Hello")
I get the expected plot.
HOWEVER, if I put the following in a cell and hit Run Code, I get nothing.

run query using rexcel runrfile and rodbc sql query
Hi,
I'm using R-2.8.1 for windows. I wrote a script calls the RODBC
package to run sql queries against an oracle database. It runs fine
when run from the rconsole and returns a data.frame with a summary for
a set of experiments. I want to run this script using the
rinterface.RunRFile command in an excel plugin, using the rexcel
package. When I run the code from my excel plugin I

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

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

rcom package
Hi,
I would like to make a program that reads excel files, and writes the cells of which contents is not a formula to another file. I don't think this is possible with RODBC, but it may be possible with rcom.
I read the documentation of the rcom package, but I was hoping somebody knows a good web resource for more eleborate info. I tried Googling, but alas (did you know rcom also is a

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?

Use of R in Schools
I am looking for information on experimentation with the use
of R in the teaching of statistics and science in schools. Any
leads would be very welcome. I am certain that there is such
experimentation.
I've made this inquiry on r-sig-teaching, with no response.

apply on large arrays
I have a big contingency table, approximately of size 60*2*500*500,
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:

tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0))
tab3<-apply(tab2,1,sum)
Computing tab2 is very slow.

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.

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)

Dates and times from Excel
I have used xlsReadWrite to read data from an Excel spreadsheet.
I had a problem with converting times of the day so that I could create
POSIXct date-time objects. I was wondering if there was a better
solution.
Excel stores times of the day as fractions of a day so I wrote a function
to convert the fraction to a number of seconds, extract the hours, minutes
and seconds and output it in ISO

R and Excel
Even using the VBA back of Excel to create interfaces with R would
make a lot of sense. Suppose I could have access to VBA macros that
import and export data into R , it would be great.
The R GUI series like Rattle come even closer to Excel...so a VBA
_R_ExCel package might be useful to ordinary folks .
Besides Excel costs money, so adding R functions to Open Office would

Possible uninstall problem on windows.
I just uninstalled R 2.7.2 on Windows XP after having installed R 2.8.0
The uninstaller removed the String values

I do not know if this has been reported already
(I searched the headers of the recent messages to r-devel)
It seems that 'example' in R 2.11.0 has a problem when the help file

This is what happens on R 2.11.0 on Windows XP.
