R-beta: which Linux - again
Dear all,
I think this question has been raised very recently but I think I didn't
see repsonses on the list nor did I find the thread in the archives. (If
it is there I'd appreciate directions ...)
I am about to install Linux on a Compaq notebook. One important thing I
want to do is being able to run R. I have fiddled with different
distributions of Linux (LST, SuSE, Debian) and can

character vectors in data.frames
Dear all,
well, today I just seem to run into these problems ... (I am still working
on R 0.63.1 on a SuSE 5.2). I would like to have a data.frame that also
contains character (and NOT factor) vectors. Two things that I tried (the
second worked in R 0.62.2):
> test.df <- data.frame (X= character (4))
> test.df$X [1] <- "a"
Warning: invalid factor level, NAs generated

avoiding (another) error
Dear all,
Many thanks to all who always so quickly respond with helpful hints!
Currently I am working with R 0.63.1 on SuSE 5.2 which I installed this
morning within about half an hour: my deepest compliments to the
developpers! (I had still 0.62.2 before.)
This time I am trying the following:

idea for (further) debugging ace ()?
Dear all,
I am trying to use ace on a 446 x 14 Matrix, with two categorical
variables in the first two columns. If I try to run it I get:
> aceiH <- ace (data.mat, resp, cat= 1:length(x.cat))
Error: NAs in foreign function call (arg 3)
There is only one .Fortran call in ace () with the third argument being
x = t(x). Thus I tried to debug ace, i.e. I went through ace until just

Dear all,
The following works with a simple result of lm but gives the error with a
more complicated one (could this be due to singularities that occurr in
the model?).

.Rdata questions
Dear all,
in a current project I have a pretty huge .Rdata. Thus I was working with
R --vsize 100 --nsize 1000000. Today when I tried to restart R I get the
following error message:
Error: a read error occured
Fatal error: unable to restore saved data
(remove .RData or increase memory)
I increased memory up to --vsize 180 and --nsize 2000000, but the error
reoccurrs. Is there a way to know

image ()
Dear all,
I am working with R Version 0.62.2 (July 10, 1998) on a SuSE Linux 5.2.
I have troubles in understanding the function image (). Can someone
enlighten me?
I'd like to draw a square image-plot (with every little part of the image
a square as well) and add some (straight) lines to it. Also, I create an
empty z matrix which I need to fill step by step. Thus I tried to find out

Symbols for male/female
Dear all,
I would like to use the biological symbols for male and female as plotting
symbols in a scatterplot (ideally filled and non-filled). R does not seem
to have these symbols using pch= in plot() nor are they implemented via
expression() or at least I did not find them. I found that the symbols are
e.g. available in the wasysym and the marvosym package in LaTeX.

openssh-3.7.1p1 -- openbsd-compat/inet_ntoa.h missing
Hello
I just installed openssh-3.7.1p1 on IRIX64 6.5 04100802 IP27.
The compilation failed since the header file
openbsd-compat/inet_ntoa.h
was missing. I downloaded the package from different sources including
ftp.openbsd.org, there was no difference.
Since inet_ntoa.c has not been changed, copying the inet_ntoa.h from
openssh-3.6p1 fixed the problem.
The package should be fixed anyway.

Dear R users,
I have not found anything on this in the archives. Does anyone know whehther
the parameter use= is not functioning in cor or enlighten me what it is

glmmPQL - predict (..., type= 'response')?
Dear R users,
Is there something like predict (..., type= 'response') for glmmPQL objects
or how would I get fitted values on the scale of the response variable for
the binomial and the poisson family?
Any pointers are appreciated.
Thanks, Lorenz

dfs in lme
Dear R-mixed-effects-modelers,
I could not answer this questions with the book by Pinheiro & Bates and did
not find anything appropriate in the archives, either ...
We are preparing a short lecture on degrees of freedom and would like to
show lme's as an example as we often need to work with these. I have a

Samba Share of NFS filesystem
We have a samba share which is a NFS mounted filesystem with user quota.
The samba server runs SuSE 9.2, the samba version is 3.0.20b. The
filesystem is nfs mounted from a NetApp fileserver.
If a user on a windows (xp or 2k) client copies some files onto his
samba share and needs more space than the quota allows, the copy
operation ends without any error message! As I have seen in the samba

Partially crossed and nested random factors in lme/lmer
Hi all,
I am not a very proficient R-user yet, so I hope I am not wasting people?s
time. I want to run a linear mixed model with 3 random factors (A, B, C)
where A and B are partially crossed and C is nested within B. I understand
that this is not easily possible using lme but it might be using lmer. I
encountered two problems when trying:
Firstly, I can enter two random factors in lmer but

Contrasts for ordered factors
Dear all,
I do not seem to grasp how contrasts are set for ordered factors. Perhaps someone can elighten me?
When I work with ordered factors, I would often like to be able to reduce the used polynomial to a simpler one (where possible). Thus, I would like to explicetly code the polynomial but ideally, the intial model (thus, the full polynomial) would be identical to one with an ordered factor.
