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

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:
tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM))
tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0))
tab3<-apply(tab2,1,sum)
Computing tab2 is very slow.
Is there a faster

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)

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?

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
HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\Current Version
HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath
despite the fact that they pointed to R 2.8.0
The uninstaller did not remove the key
HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2
(and all the values in that key)

exmaple problems
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
does not contain any example.
This is what happens on R 2.11.0 on Windows XP.

histogram question
hist(rbinom(1000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,300))
gives a histogram with "touching bars"
hist(rbinom(100000,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000))
gives a histogram with space between the bars.
is there a way to control the space betweent he bars easily?

factor always have type integer
typeof applied to a factor always seems to return "integer",
independently of the type of the levels.
This has a strange side effect.
When a variable is "imported" into a data frame,
its type changes.
character variables automatically are converted
to factors when imported into data frames.
Here is an example:

New unique name
In some languages there is a function
gensym()
which returns a new unique name (in the current environment).
This is quite helpful when one has to do temporary assignments.
I could not find such a function in R.
Is there one?

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.

warnings details
I am running R as an invisible subprocess in another program (RExcel).
Using try I can catch errors and print the errors produced by an R
statement.
Is there a way to know if running a statement caused a warning message?
last.warning gives me the last warning, but I do not have any indication
what the statement was that caused the message.
I can of course store last warning before I run
