(no subject)
Dear all,
Is there a quick and easy way of converting utf characters to the \uxxxx
form (necessary e.g. for packages)? I mean something working like this:
> utf2uxxxx("õäöü")
[1] "\u00f5\u00e4\u00f6\u00fc"
It is easy to program but perhaps someone already has implemented this. (I
couldn't find anything useful from searches incl RSiteSearch).
Thanks in advance,
Kenn

sqlFetch (RODBC) question
Dear all,
I've used RODBC a lot to read in files created in MS excel and access but
found a strange problem today: a variable in my data file contained both
numbers and text; sqlFetch would set text within a row of numbers to NA; but
if first 5 or 6 rows would be text then all numbers would be read in as NA.

Preserving the class of POSIXt objects
Dear all,
I am working with a list of objects each of which contains two POSIXct
objects (say, $Start and $End) and a number of different data in
addition to that. Now an easy way to extract Start times of all object
could be sapply(x, "[", "Start") but this converts them all to
numeric, and so does sapply(x, "[[", "Start"). lapply preserves the
class but

Q-type factor analysis
Hallo!
Is there a package in R that does Q-type factor analysis?
I know how to do principal component analysis, but haven't found any application of Q-type factor analysis.
Thx,

Password-protect R script files
There was a question in R forum very long time back.. on how to protect R
Script files from inadvertent editing by users.
There is a way to do this from within R, atleast in Windows XP I have tried
this and it certainly works , The method is very different from the OS
based folder protection route, however making available such a method in
the open forum would only kill the very spirit of R.

cov2cor exp
Ok, Thanks foe the answer, Ken:
*1L, 2L etc are integers. (That is, identical to as.integer(1) ,
as.integer(2) etc)
Using integers (instead of "numeric" type) is more efficient as here they're
used as indexes and would be converted to integer anyway.
Compare
> is(1)
... and
> is(1L)
1L:p is the sequence 1, 2, 3, ..., p (just like 1:p)

Curry with `[.function` ?
Dear all,
I sometimes use the following function:
Curry <- function(FUN,...) {

https://stat.ethz.ch/pipermail/r-devel/2007-November/047318.html
.orig <- list(...)
function(...) do.call(FUN,c(.orig,list(...)))
}
... and have thought it might be convenient to have a method for [ doing
this. As a simple example,

Xen 4.0 with Remus on Suse 10.1??
Hello,
I am trying to set up a Xen/Remus test configuration on AMD64 hardware
(HP DL380 G6) under SuSE 10.1 and am having trouble.
I was able to run and configure the Xen 3 that came with SuSE fine, but
as far as I can see, I have to use Xen 4 to get Remus.
I managed to build Xen 4 from source and it seemed to install, but I am
not sure how to get the proper kernel and/or initrd files in place

Consecutive zeros in a vector
Suppose X is a long vector of integers (typically about 30000 elements). Is
there an efficient way to detect whether there are at least N consecutive
zeros in X, and if yes, where does this occur?
for example, suppose X is:
1 2 3 4 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 4 2 0 1 2 0 0 0 2 2 2 2 2 ...
and N is 10. I would like a foo(X, 10) to return something like c(6,19)

bootable dvd
Is it possible to use isolinux to create a bootable dvd? I have a .iso
that boots fine from cd but not from dvd.
I have a Dell OptiPlex GX240 with dvd/cd drive. Dont know for sure if
the bios requires an update to boot dvd.
Any info would be appreciated.
Thanks,

suggestions re trunc.POSIXt
Dear all,
I hope this is a right place to post this; r-help might be appropriate
but it looks like I'm suggesting a change in base package, so I
decided to post here. (+ Apologies if that has been changed recently
-- the version I'm using is R.2.12.2 on Windows.)
I've noticed an unexpected behavior of trunc.POSIXt:
foo <- seq(as.POSIXct( "2009-10-23 22:00:00"),

Notes and warnings in building a package ('ms-dos style file name', 'no visible binding' and using .C("bincount", ..., PACKAGE = "base"))
Dear all,
While buildign a package (R 2.15.2 on windows XP) I had three
warnings/notes -- I would be grateful for any hints on what to do.
1. The first one is probably not really important if I'm not missing
something:
cygwin warning:
MS-DOS style path detected: C:/x/y/z/package_1.0.tar.gz
Preferred POSIX equivalent is: /cygdrive/c/x/y/z/package_1.0.tar.gz

Recursive objects
Hi all,
Does anyone have a comprehensive list of recursive-type objects in R?
is.recursive defines them as by exclusion: "most types of objects are
regarded as recursive, except for vector types, ?NULL? and symbols
(as given by ?as.name?)." I think this that means recursive objects
are:
* lists
* pairlists
* calls
* expressions
Did I miss anything?

Subsetting an array by a vector of dimensions
Hi
Is it possible to subset an n-dimensional array by a vector of n dimensions? E.g. assume I have
> x <- array(1:24, dim=2:4)
> x[1,1,2]
[1] 7
> dims <- c(1,1,2)
I would like a function that I can supply x and dims as parameters to, and have it return 7. Also, I would like to do something like:
> x[1,1,]
[1] 1 7 13 19
> dims2<- c(1,1,NA)
And have a function of x and

Help me apply mapply
Hello all I would like to ask your help use mapply.
I have a function called findCell that takes two arguments(x,sr)
where x is a vector of size two (e.g x<-c(2,3) and sr is a matrix.
I would like to call many times the findCell function (thus I need mapply) for different x inputs but always for the same sr.
as x is a vector of size two (two cells) I want to pass inside inside the following
