Warning in par(args)
I'm getting a lot of warning having to do with setting graphic parameters. I
don't recall actually setting any of these, so I would guess they are being set
by something I am calling. Has anyone already figured out where this is
happening?

Inferring dimensions on bitmap device from par()
Hi,
I am trying to infer the dimension of an opened bitmap (png, jpeg,
bitmap device...) from par() parmeters. From the help on par(), I
found that:
> dim <- c(400, 200)
> png("foo.png", width=dim[1], height=dim[2])
> dim2 <- par("din") * par("cra") / par("cin")
> dev.off()
> dim2

Dear R folks,
Initially I had a plotting routine using logarithmic y-axes that failed after
repeated calls if I tried to restore the graphical parameters (which I wanted to
do because I used `layout' within the routine. I tried to isolate the problem
and found out that the following code with logarithmic axis is sufficient for

Alternative to cxy in R
good morning to the R-help list!,
I would like to ask if there is an alternative to the S ploting
parameter "cxy" in R. I am trying to port some S code to R that makes use
of this "cxy" parameter to scale the graphics, and I don't find this
parameter in help(par).
thank you,

Difference in client vs. server graphics defaults
Hello,
I am having trouble with the difference between default graphic settings on
my client machine and the instance of R on our company's server. I created a
script locally that output graphs, but when I run it on the server the
output graphs have titles running past the margins, legends improperly
placed, etc. I checked the default par() settings and found differences

documentation error par("cin") and par("cra") (PR#7227)
Dear all,
the help of par() claims that

c(width, height)
but it appears to be rather

Problem with pdf device.
Hi,
I seem to have broken the pdf device on my installation. I'm running R
1.6.1 under Apple's X11 on darwin 6.3. Running the following commands
straight after starting R (and without touching 'par') gives different
results - the png file looks fine but I'm missing axes and labels on
the pdf. If I try and print the pdf, axes and labels appear but with
text characters as

Character height & width in user co-ordinates
Is there an equivalent to the S-PLUS par()$cxy in R?
Also, is it possible to get notice taken of some
equivalent of \n in R when using text()?
For what it is worth I am using RW-0.64.1.

Size of objects in the workspace
Is there an easy way (or any way) to determine the size of all the
objects in an R workspace. I know that "dim" will work on matrices,
"length" will work on lists, but what gives the size of a function?
After I have worked for a few days I often get confused about what is
what in the workspace, so I'm looking for something like "ls -l", to

par$csi
Dear R-help,
I'm using 63.3 on windows NT. The improved graphics device has a problem
in that the default par settings produce text that is way too small (63.2
seemed fine). I've compared the parameters between 63.3 and 63.2 and the
ones that differ are : cin, cra, csi, mai, pin, plt. In the par help file,
cin and cra have no documentation other than that they are read only, the

X11 and linux and plotting and the vertical axis
I use R on linux and I go through exceed from a windows machine.
Depending on the amount of plots I do on a screen, sometimes the numbers
on the vertical axis
of the plots don't show up. I tried infinite of combinations of mar and
cex but nothing helps.
Yet, if instead of shooting the graphic upto the screen, I send it to a
pdf file or
a postscript file, the numbers on the vertical axis of

Large plot symbols (with pch = 1 etc)
On my home (Windows 98) machine I find:
> par()$cra
[1] 42 16
> par()$csi
[1] 0.1666667
>
On my work machine I believe I had
par()$cra
[1] 17 16
So it looks as though R is reading the width wrongly,
and that it is the width that is somehow used to
determine the plot character size.
Incidentally I noted Brian's comment that R had misread
his character dimension information wrongly.

panel.axis() & grid/lattice settings
Hello,
I wish to customize the tick marks and labels of axes in panels produced by
high-level lattice functions, namely xyplot. I know I can use the scales
argument to specify values for rot, cex, etc. in the top-level call.
However, I am interested in determining values for cex and rot based on the
current panel / viewport and device. More specifically, I would like to make
adjustments when

Weird operator behaviour
Hi,
I have a dataset called 'fish'. fish$Species returns extract 1. When I use
fish$Species != c("CRA","PHC"), i.e. I want all species except "CRA" and
"PHC", I get extract 2 which is blatantly wrong. Can anyone see what I'm
doing wrong?
Regards,
James

Additional output in cancor
Hi everyone,
Can I suggest an additional output component in cancor, from package
mva? It would be useful to have the number of canonical correlation
vectors, equivalently the rank of the covariance between x and y (label
"rank"). This would usually be min(dx, dy), where dx and dy have
already been computed for the svd function, but there might be
situations where it was less than

Plot Character Sizes in rw-0.90.0
I have two supposedly identical installations, one under Windows 95,
and the other (at home) under Windows 98. The puzzle is that under
my Windows 98 installation, symbols plotted by default or with pch
come out huge, at about 2.2 times the height of the axis labels.
Setting cex=0.5 seems about what is needed to fix the heights.
On the Windows 95 installation, the symbols come out just a little

Hi R friends,
I havent asked a silly question in a long time so here it is:
Reading the last issue of Stat Can J. there is an article in a single
degree of freedom test for non aditivity of interactions in anova
tables with 1 obs per cell. The authors claim it is more powerfull than
Tukey but for the case of multiplicative interaction, which is the
alternative studied by Tukey. I tried to
