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

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?

help and Firefox
My configuration is Windows XP, R-2.5.1patched.
My standard browser in Windows is Firefox 2.0.6,
and I am using htmlhelp.
I have problems with starting the browser for displaying help.
help("lm") works as it should when Firefox is already running.
When I do help("lm") and the browser is not yet started,
I get

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

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)

Rprofile.site in Windows version
I think Rprofile.site as installed with R-2.6.2
contains some misleading information.
It contains the following lines
# set a CRAN mirror
# local({r <- getOption("repos")
# r["CRAN"] <- "http://my.local.cran"
# options(repos=r)})'.
Uncommenting these lines and changing the URL
will not work.

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)

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.

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.

RE: [Rd] converting body of a function to a a character vector
1. This query belongs in r-help, not in r-devel
2. Pity about your shift key...
3. The function you need is deparse() rather than as.character():
> fff <- function(x) {
+ x*x
+ }
> deparse(body(fff))
[1] "{" "x * x" "}"

4. There is a reason why as.character works this way. It transforms to
character from a more fundamental representation of

dataframes with only one variable
Subsetting from a dataframe with only one variable
returns a vector, not a dataframe.
This seems somewhat inconsistent.
Wouldn't it be better if subsetting would respect
the structure completely?
v1<-1:4
v2<-4:1
df1<-data.frame(v1)
df2<-data.frame(v1,v2)
sel1<-c(TRUE,TRUE,TRUE,TRUE)

Get official and unofficial fixes for Excel

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.
