unequalspaced time-series data
Dear R-users,
is there any object-type or routine/function in R which can handle
unequally spaced time-series data? I know that there is the library
OSWALD for S-Plus, which is able to do so, but I was not successful in
running it under R. Does anyone can help?
Thank's in advance!

objectname completion
Dear R users,
is there any possibility to get an object-name completion within the R
command line (UNIX-version of R). As I got to know from the FAQ that
this is possible from within Emacs (ESS), but without using Emacs?
Thank's
Ingo

Trend test for survival data
Hello,
is there a R package that provides a log rank trend test
for survival data in >=3 treatment groups?
Or are there any comparable trend tests for survival data in R?
Thanks a lot

Sourcing files with library
Hi everyone,
I have written a class with methods that extend generic functions such as
as.data.frame or show. When I load this package, I want to ensure that
these methods - along with the other functions in the file - are added to
R's search path or updated, if necessary. I have made a package using
check/build/INSTALL.
Will a simple library() call on the package accomplish this? I

KS for goodness of fit
Dear All,
I have two distributions which I don't their nature. I want to check whether they come from the same distribution. I know that I can use KS test however the standart function ks.test applies only the ks test for testing the difference of two samples (non-parametric). By the way the distribution are of Euclidean distances. One of observed and the other of shuffled data.

Refactor all factors in a data frame
Hi all,
Assume I have a data frame with numerical and factor variables that I
got through merging various other data frames and subsetting the
resulting data frame afterwards. The number levels of the factors seem
to be the same as in the original data frames, probably because subset()
calls [.factor without drop = TRUE (that's what I gather from scanning
the mailing lists).
I wonder if

More on scan()
Hi,
If I have a CSV file which has several comments at the top, and the data
start immediately after the line:
@DATA
Is it possible to use the scan() command to get the CSV data into R, by
only reading the lines after @DATA? If so, how can I do it?
Cheers,
Kevin

How to comment out multiple lines in R source code?
Hi,
Is there a way to comment out multiple lines at once in R source code like C
language's /* */ struct?
This is quite useful when one is testing different sections of a source
code.
Thanks,
Jonathan

Font size of axis labels
Hi all,
In R, it is not possible to set the font size of axis labels directly
(AFAIK). Instead, scaling factors for the font chosen by the graphics
device can be supplied. It appears that there is no constant font size
for axis labels. My impression is that the axis label font size is
scaled internally by R depending on the number of labels given for an axis.
In addition to the R-internal

adding logical vector to data frame
Hello. I'm afraid that I'm missing something very obvious this
afternoon...
When I add a column to a data.frame (by assigning to a "new" column
name a logical vector), I thought that I had (at least) 3 options to
do so:
R> j <- data.frame (x=1:2)
R> j$y <- c(TRUE,FALSE) #assignment 1
R> str(j)
`data.frame': 2 obs. of 2 variables:
$ x: int 1 2
$ y: logi

OT: ps -> eps -> MS Word
I've created a bunch of postscript trees (post.rpart), which I subsequently
edit in Adobe Acrobat 4.05 (I need additional labelling that isn't easy to
add with R). After editing the labels and annotations using Acrobat, I
then export the file to Adobe's .eps format so I can insert the picture
into a Microsoft Word 2000 document. The .pdf file distilled from the .ps

?? hmm ??
Hello again!
thanks to all who helped with overlay plots - v. easy in the end.
Anyway, another new(ba)bee type question - the gurus will cringe I'm sure!
Q. simple R function
mm <- function (u) {
x <- u$GDP
x
m <- mean(x)
m
}
When the function is called the vector "x" does not get printed from within
the function, but the mean value "m" does, why?

Sparse matrix methods
Does anyone know of contributions to R for solving sparse linear systems?
In particular for spatial stats I am interested in solving large
positive definite symmetric systems.
Thanks in advance,

residuals in lme4 package
Hi,
I have not been able to calculate residuals in the lme4 package. I've
been trying the resid() function after I ran a GLMM with the lmer()
function, but I get an error message that says "residuals are not
inserted yet". I looked it up in the "help" history and I realized that
several people have had this problem in the past, related to some bug in
