graphical paramters to boxplot
Dear all,
is this a bug or do a miss something (this concerns version 0.63.1 on
Linux)?

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

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

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?).

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

.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

lm with rank-deficient X matrix
Dear all,
I would like to fit an lm in which a subset of the explanatory variables
are linearly dependent. Thus I would like to include the restriction that
all betas of these variables sum to 1. Is there a way to this in R? Or is
this what happens automatically if I set singular.ok= T (which is the
default, I believe)?
Thanks for your help. Lorenz

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

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.

Change page in postscript()
Hi,
Another question about graphics...
Suppose I have:
par(mfrow = c(4, 6))
which will set up a figure region for 24 plots. But, I actually only need
23 plots. In fact I wrote a little function, foo.plot, which will draw
all the 23 plots at once with:
foo.plot(x)
where x is a data frame.
Now, suppose I want to draw several set of these 23 plots, but want to put
them all in one postscript

grouping for lme with nested repeated measurements
I am using lme to handle repeated measurements.
So far i can follow the examples from the book from pinheiro and bates.
Now i get the problem , that i have "nested" repeated measuremnts, and i cant find out how to do the grouping part of the lme formula.
1.The simple problem ist that i have different Samples , from which i make repeated measurements (each sample is measured 6 times) and

exporting data to csv file -problem with column names
I have a data.frame with three columns + the row number
Sample MidPoint Count

When I export the data to a csv the column names are shifted because
the row numbers are being exported as well.

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.

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.

Split-split plot ANOVA
Does someone out there have an example of R-code for a split-split plot ANOVA using aov or another function? The design is not balanced. I never set up one in R before and it would be nice to see an example before I tackle a very complex design I have to model.
Thanks,

multiple error strata in aov
I am trying to perform a model 3 ANOVA for a 2 factor (say factor A and
factor B) anova in which factor A is fixed and factor B is random.
Therefore, the error term for the test of factor A should be the A:B
interaction term and the error terms for B and A:B should be the model
residual (within) term. I have tried to work out how to specify such
error strata using aov, however, I have had

Bug in my code (finding nonzero min)
Can someone verify for me if the for loop below is really calculating the
nonzero min for each row of a matrix? I have a bug somewhere in the is
section of code. My first guess is how I am find the the nonzero min of each
row of my matrix. The overall idea is to make sure I am investing all of my
money, i.e. new.set is a set of indicator variables for each stock for a
particular portfolio, i.e.
