is there something like or() ?
hi, this may be trivial, but we can't seem to find anything adequate,
(although there is a work around with match() ). We are looking for something
along the lines of
plot(table1[table1$var2==or("a","b","c","d"),"var1"])
would be handy, with the potential or() function leading to what
plot(table1[table1$var2=="a" |

write data from function into external table
Dear list,
My apologies if a solution / explanation to this already exists on the list,
but it is difficult to assign it to a certain keyword.
test<-c(1:3)
testfct <- function(x) {test[1]<-100}
test
[1] 1 2 3
testfct(1)
[1] 1 2 3
Basically, I would like to write data into an external table that the function
does not know. Why is this not working / what alternatives exist?
Thanks,

common axis label in multiple plot area
Hello
A very short question: Using multiple plots with par(mfrow=c(3,3)), how
can I get R to indicate one common y- and x-axis label? I tried to use
text() in par, but this is then overwritten when I plot the graphs.

Editor for Mac OSX
Dear R-list
I am (forced) to change from Linux to Mac and am now looking for a new editor for R. I would like one that features a split window (console + editor) as well as syntax highlighting. Can anyone help? Especially the split-window feature does not seem to be easily available in the editors desribed on the R-help site, except Emacs, which I am reluctant to start using. I am on a MacBook Air

stl()
Hello, anyone got an idea on how to use stl() so that the remainder eventually
becomes white noise? i used stl repeatedly but there is autocorrelation in
the remainder that i can't get rid of.

interruption when pasting code into R under linux
hello,
has anyone come across the following rather mysterious problem:
when pasting large bits of code (100 and more lines) into the R console with
the central mouse button (under linux), only part of the code is pasted, and
the text interrupts somewhere arbitrarily. It does not happen when smaller
bits are pasted subsequently.
I use linux suse 9.3 with the latest version of R

suppress tick labels
hello,
is R able to suppress tick labels (not tick marks)? i know there is a way
around this with axes=F and then draw new axes, but it would be easier to
suppress them in the first place.

I run suse linux 9.1 and I installed MySQL server, client, devel, bench.
DBI is installed, when I try to install RMySQL I get an error saying,
that libz is missing.

Tukey HSD following lme
Hi everyone
I'm using Tukey HSD as post-hoc test following a lme analysis. I'm
measuring hemicelluloses in different species treated with three
different CO2 concentrations (l=low, m=medium, h=high). The whole
experiment is a split-plot design and the Tukey-function from the
package multcomp is suitable for lme-analysis with random factors.
The analysis works fine but I get a non

binomial lmer and fixed effects
Hi Folks,
I think I have searched exhaustively, including, of course R-help (D.
Bates, S. Graves, and others) and but I remain uncertain about
testing fixed effects with lmer(..., family=binomial).
I gather that mcmcsamp does not work with Do we rely exclusively on z
values of model parameters, or could we use anova() with likelihood
ratios, AIC and BIC, with (or without)

Remove missing observations
Hi everyone
I have the following problem: My dataframe has 3 variables: ID, Year and
and an outcome variable. The dataframe contains repeated measurements
because the subjects filled out a questionnaire every year. The time span
covers 2 years.
Now I want to check if there is a significant change in the outcome over
the 2 years with a paired wilcox.test. The problem: Not every subject

How to handle large dataframes?
Dear all
I imported a Stata .dta file with the read.dta-function from the
foreign-package. The dataframe's dimensions are
> dim(d.apc)
[1] 15806 1300
Importing needs up to 15 min and calculations with these data are rather
slow (although I subset the data before starting analyses).
My questions are:
1. Has someone experiences importing Stata files (alternatives to
read.dta) ?

overleap an iteration within a for-loop when error message produced
Dear R-list member,
I'm using the function pmnorm() (-->library(mnormt)) within a for-loop.
Certain parameter values leads to an error message:
"(In sqrt(diag(S)) : NaNs produced, In sqrt(1/diag(V)) : NaNs
produced, In cov2cor(S) : diag(.) had 0 or NA entries; non-finite result
is doubtful)"
obviously because "NaNs" were produced.
Is it possible to tell R that it

dendrogram branches with different lty
Dear r-list,
I am trying to visually seperate the two main clusters of a dendrogram.
The idea is to use:
'edgePar=list(lty=3)' for 'dend1[[1]]' and
'edgePar=list(lty=1)' for 'dend1[[2]]'
I have not found a way to solve this. Any suggestions?

pdbedit syntax for forcing user to change password
Hi all
Maybe a stupid question, but I'm not able to figure this out from the
manpage nor from the HOWTOs...
How can I force a user to change his password at next logon?
I tried:
# pdbedit -P "user must logon to change password" -C 0 -u username
# pdbedit -u username -P "user must logon to change password" -C 0
# pdbedit -P "user must logon to change password"

shrinkage estimates in lme
Hello. Slope estimates in lme are shrinkage estimates which pull the
OLS slope estimates towards the population estimates, the degree of
which depends on the group sample size and the distance between the
group-based estimate and the overall population estimate. Although
these shrinkage estimates as said to be more precise with respect to the
true values, they are also biased. So there is a

retrieving p-values in lm
Dear list,
I want to retrieve the p-value of a two-polynomial regression. For a
one-polynomial lm I can easily do this with:
summary(lm(b~a, data=c)[[4]][[8]].
But how do I find the final p-value in the two-polynomial regression? Under
$coefficients I don't find it
Any suggestions?
