construct a bundle, subdirs do not exist?
Hi,
Sorry to bother, but I checked around and did not succed creating a
bundle from six existing packages (which are checkable, installable,
etc. individually). I carefully followed the procedure given in ch.
1.1.5 Package bundles. However, I am getting

regular expressions, sub
Hi,
I am trying to use sub, regexpr on expressions like
log(D) ~ log(N)+I(log(N)^2)+log(t)
being a model specification.
The aim is to produce:
"ln D ~ ln N + ln^2 N + ln t"
The variable names N, t may change, the number of terms too.
I succeded only partially, help on regular expressions is hard to
understand for me, examples on my case are rare. The help page on R-help

I am getting masked objects and I think the maintainers of the

Hi list,
I have not been successful in finding out from the available

linear lists, creation, insertion, deletion, traversal *someone?*
Hi,
In a second try I will ask this list to give me some useful pointers.
Linear lists, as described e.g. by N.Wirth in "Algorithms and Data
Structures", seem not to be implemented in S/R, although in lisp we have
cons, car, cdr.
Nevertheless I want to implement an algorithm using such linear lists,
porting a trusted program to R (S). I need:

paired repeated measurements
I have the following problem:
I measured co2 on 6 paired sites (one grubbed and one non-grubbed
fence per site -> grubbing = treatment). These measurements I repeated
15 times over 2 years. So, now my problem is how to analyze these
data. I tried the following model:
mod1_CO2<-lme(co2~treatment+time,random=~1|site,data=CO2_t1_t15)
I think with the random effect I included the paired

vector to matrix transformation
Dear,
Some analysis (linear regression) can only be
done from a vectorized dataset whereas others
require a matrix (Mantel tests). I use the two
analyses and thus need to format my data in
matrix and vector. I spent some time trying to
solve the problem and I just gave up. Did anyone
knows how to transform a matrix into a vector and
back-transform a vector into a matrix?

How to retrieve a method

I am interested in the inner workings of wilcox.test:

how can I get at the code, if it is R-code? For Methods one should be able to learn what extension to use, but here default or such do not help.

logical and NA
Hi there, (sorry Martin, ich habe den falschen Empfaenger erwischt :-( )
Is there a function in the base package or elsewhere which returns TRUE and
not NA, even if NA is involved: (I did not find in the help system :-( )
if ( x==something & !is.na(something))
or
if ( x==something & !is.na(x==something))
If "something" is complicated, a function would be handy.

"chemical" plot
Hi all,
May be there is a plot which shows 3 variables in a triangle, their sum
being constant. I have forgotten its name, and a search in the engine using
"plot" did not help.
Does anyone know of such a procedure in R or S?
Thank you

Plit result of pairs in an Sweave compatible manner
Hi,
I want to use "pairs" on a fairly big matrix, say more than 30 columns.
R tries to fit this on one page, which results in tiny invidual
rectangles, and dots are hard to see.
Is there a way to transform the output of pairs in a way that subplots
of 10*10, say, rectangles are generated. These subplots should then go
to Sweave which is accepting one figure at a time presently.

(no subject)
Hi,
I would like to know if it is possible to get printed output while a loop is taking place.
Example:
for(i in 1:10){
print(i)
some long process
}
This will print the values of i only after the loop is finished, what I would like is to
see them when the process enters the i-th iteration to keep track of how the
program is running.
Thank you,

curve fitting to data
Hi to all
This is the first time I am quoting a question and I hope, my
question is not too basic...
For the following data, I wish to draw a fitted curve.

setkeys and Sweave
Hi there:
Using
\setkeys{Gin}{width=1.0\textwidth}
\setkeys{Gin}{height=10cm}
\setkeys{Gin}{height=0.8\textwidth}
all seem to work under R-2.1.1 under sparc, solaris2.9, but
\setkeys{Gin}{scale=0.3}
\setkeys{Gin}{angle=90}
do not work. I have not been able to find relevant information, googling
on setkeys proved confusing, at best.
