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

apply on large arrays
...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 and/or more elegant way of doing this?

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?

Nice reference to R
...rian Livingston
Despite the hotfix that Microsoft recently released for Excel 2007, as
I described on Oct. 11, some math errors that you should know about
still lurk in both Excel 2007 and Excel 2003.
I'll bring you up to date and explain how you can get better results from Excel.
Baier and Neuwirth offer Excel math add-ins
In a nutshell, this month's patch for Excel 2007 corrects a bug that
treats numbers close to 65,535 as if they were 100,000. To get the
fix, see the Oct. 9 entry in Microsoft's official Excel blog.
Even with the hotfix, however, both Excel 2007 and Excel 2003 give...

Evaluating expresssions as parameter values
I need to play games with an expression similar to the following one:
print(xyplot(DepVar ~ Group|Covar, groups=Othergroup,
data=mydf, pch = 18 ,main="Testcase",auto.key = TRUE))
The problem is that the formula argument (the first argument)
an the groups argument are passed over from another program as strings.
The formula argument does not pose problems,

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(df$v2)
[1] "integer"
It is somewhat surprising that
the types of v2 and df$v2 are different.
the answer is to do
levels(df$v2)[df$v2]
but that is somewhat involved.
Should the types not be identical, and typeof applied to factors
return the type of the levels?

Rpad and R 2.10.0
...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 opens.
Has anybody else similar experiences?
Can anybody offer advice?

Possible uninstall problem on windows.
...it happens and when not.
Sometimes also running RSetReg.exe creates a second entry like
HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2
which has identical content with the first one.
The registry really looks like having 2 identical entries.
Is this something which I should file as a bug?

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)

question
...on would be running a stdin-stdout version
of the server through inetd.
but this is vulnerable.
so what is needed is a sandbox version of the server,
where no acrtive access to the file system is open
and where spawning processes is disabled.
are there any plans for doing such a version?
