"Groups" in XYPLOT
I'm not sure I'm barking up the right tree here, but would I need to make
use of groups to plot two separate datasets within ONE panel in xyplot? The
desired end result is a single xy plot of two separate (but similar in
values and ranges).

jpeg() saving blank files?
Hi,
I am having trouble saving graphics from R. jpeg() saves a file with
the correct name to the correct directory, but it consists of a blank
(white) jpeg with the specified dimensions--the image itself is not
being saved.
My code is
jpeg(filename="myfile.jpg",
height = 2.5, width = 8, units = "in", res = 72,
pointsize = 12, quality = 100, bg = "white",

Problema con el tamaño de las letras en R en gráficos multiples
Hola buenas,
Actualmente me hayo haciendo unas gráficas que han de tener un tamaño de
letra determinado. Para ello empleo los parametros ps de las funciones
x11() y en par().
Mientras hago gráficas de uno y gráficas de dos plots todo va bien. Pego
las gráficas en power point y veo que las gráficas son del tamaño
recomendado (pego una caja de texto y compruebo que todo es correcto de

Too long pathname in bitmap() crashes R on WinXP
Hi,
using too long pathnames for bitmap() crash R on WinXP. I've verified
that this is the case with R version 2.4.1 Patched (2007-03-25 r40958)
and R version 2.5.0 alpha (2007-03-30 r40957). I cannot reproduce it
on Linux.

High resolution plots
Is there any possibility to get high resolution plots in a windows xp
system?
I tried it with the device function png(filename =
"c:/r/highresplot%d.png",pointsize=12, res=900)
but when I try to set: width = 480, height = 480 or pointsize = 12,
the text is not scaled in the same way as the plots.

Off-topic: (Simple?) Random Sampling when n is a random variable
Hi everyone,
I'm involved in a discussion with a colleague. He suggested a sample
design for a finite-sized process that (to all intents and purposes)
involves tossing a coin and examining the unit if the coin shows
Heads.
I should emphasize that we're both approaching the problem from a
design-based sampling theory point of view. So I have no argument
about the appropriateness of the

Interrater and intrarater variability (intraclass correlation coefficients)
Hello!
I want to calculate the intra- and interrater reliability of my study. The design is very simple, 5 raters rated a diagnostic score 3 times for 19 patients.
Are there methods/funtions in R? I only found packages to calculate interrater variability and intraclass correlation coefficients for matrices of n*m (n subjects, m raters) - I have n subjects, m raters and r repetitions.

Changing predictor order in lm()
Dear community,
can anyone provide a snippet of code to force the lm() to fit a model with
terms in the formula in an arbitrary order? I am interested in something
like:
lm(y ~ A * B + C, data=data)
where the interaction of A and B should be in the formula before C. My
goal is to simplify my presentation of models using the anova() statement.
I have found that this should be possible using

Lattice, ggplot, and pointsize
Hi!
When inserting R plots into a document using odfWeave, I fought for a
while to get Lattice plots use the same text size as base plots. I
eventually discovered that specifying a point size via e.g.
svg(pointsize=10) has no effect on Lattice plots. One needs to adjust
the size manually via:
trellis.par.set(fontsize=list(text=10, points=8))
This is also developed for both Lattice and ggplot2 by

pointsize - what is wrong?
Hello!
When I am trying to produce plot with text with pointsize 30 or
greater R sets up a default pointsize of 12 on plot.
I need to set up a large pointsize to make large jpeg or
png files (with good resolution).
I can write text on plot with pointsizes 18,20,22, but i cant
write text with pointsizes 25,26 and greater and i can not
understand - why? Is there are any restrictions in R? Or what?

ugly in plotmath: frac(1, sqrt(...)) (PR#1101)
Sometimes (dependent on device and settings of 'cex' and 'lwd') the line
of a square root symbol plottet in the denominator of a fraction appears
to be in or above the line of the fraction.
Examples:
### Choose one of these:
# pdf("test.pdf", height=6, width=8)
# bmp("test.bmp", width=1100, height=800, pointsize=12)
# bitmap("test.tif",

pointsize in png graphics
Dear all,
I'm trying to produce 2 png files, one consisting of an image plot and a
color-table (also an image plot) and the other one consisting of 4 image
plots and a color table. I'd like the color table to be exactly the same.
The way I proceded is the following:

Export a plot/figure to excel or word?
Hi all,
I have created forest plots using the package "meta" that I submitted as pdf for publication. I just received an email from the editor asking me if I could send these files in an Excel or MS Word format such that they can treat them as tables with box plots.
I am not sure if I can do this... Is this possible? I've tried the capture.output command, but I get a blank MS Word

problem with lattice tiff or bitmap: character size and color
Hi all,
I am trying to make tiff files of lattice plots at a resolution greater
than 300 dpi required by a journal (PLoS ONE). I have tried both the tiff
and bitmap functions. tiff keeps panel colors but reduces axes and tick
labels so they are nearly invisible. bitmap maintains correct label size
but only produces greyscale. Regular plots work fine with tiff; the
problem is only with lattice

trouble getting output from graphs, again
It seems like every time I try to do something a little different, I
cannot get output saved just right.
This is on RedHat 7.2 with R 1.4.1.
The png output looks fine, but the eps output has the problem that the
bounding box on the legend cuts the legend in half. I put a copy of a
bad one here:

I made a plot, but after I made a second plot, the previous plot was
gone. How can I save all the plots in a file (I do not manually copy
