draw a 5cm x 3cm rectangle
Hi I want to draw sth in a pdf file with a predefined defined size.
Say a 5cm x 3cm rectangle (a ruler):
pdf("rect.pdf", paper="a4")
plot(c(1,5,5,1,1),c(1,1,3,3,1),asp=1,axes="n")
dev.off()
but how do I fix that one unit is 1cm?
Thanks

unicode only works with a second one
I'd like to paste a zodiac sign on a graph, but it only prints it when
I add another unicode ( \u3030) to the desired \u2648 - why?
See the examplecode (compare the orange with the skyblue):
plot(c(-1,1),c(-4,-2),type="n")
text(x=0,y=-3.0,labels="\u2648 \u3030",cex=2.3,col="skyblue")
text(x=0,y=-3.2,labels="\u2648",cex=2.3,col="orange")

rgl: ellipse3d with axes
Last week I asked about data ellipses with rgl:::ellipse3d() with lines
showing the principal axes.
(The goal is a visual demonstration of PCA as a rotation of variable
space to component space.)
I was trying, unsuccessfully, to use princomp() to generate the PCA axes
and plot them using
segments3d:
> > PC <- princomp(trees)
> > sdev <- PC$sdev # component standard

drawing a circle using symbols
Dear friends, I was drawing a circle with centrum in (1,-1) and
radius 5 to show my girl that the line y=3*x+1 goes through (1,4) and
(-2,-5) of the circle, but on Windows XP, R 2.20 the drawing was not
good at all, and the known solutions were not shown in the graph. I
guess I got it wrong? Is this use not intended ?

internet proxy settings (win)
I cannot access internet through R.
My IT-guys told me that I should set the proxy and the port and then
everything will be fine. Where can I set them?
I use R 2.6.2 under Windows 2000 and these settings are those of the
Internet Explorer (no password).

Roman numerical output
I have integers and I want R to give them back/output as Roman numerals:
s=c(7,17)
format(s,roman=T)
is obviously wrong. Is there any other way/function to do this?

pie() with only 180°
I want to plot the results of today's elections in Austria in this
typical 180?-piechart (and not 360?).
Unfortunantely pie() has just an argument "init.angle" and no "end.angle".
Perhaps you know a workaround.

package to convert coordiantes to timezone
Is there a R-package with a function that returns me the timezone, if
I hand over longitude and latitude?
I know online services like
http://ws.geonames.org/timezone?lat=-38.01&lng=147 and
http://www.earthtools.org/webservices.htm#timezone and wodner if this
exists for R too.
Thanks for helping,

strange behaviour of CairoPNG
Hi,
could it be that the text() fuction gives different output for normal
png() and CarioPNG()?
See the following example and the attached images: the font=2 and
font=3 seem to be exchanged!
Thanks for help,
Thomas

[Package car/data.ellipse]: confidence intervals off by factor sqrt(2)??? (PR#2584)
Full_Name: Volker Franz
Version: Version 1.6.2 (2003-01-10)
OS: Debian
Submission from: (NULL) (192.124.28.104)
Hi there,
it seems to me that data.ellipse of package "car" (Version 1.0-1)
produces confidence interval's which are too big. To see this, do:
library(car)
plot(c(-2,2),c(-2,2),pch=0)
data.ellipse(rnorm(10000),rnorm(10000),levels=0.68,plot.points=F)

convert lines to inches
Hi,
how can I convert the unit "lines" of par("mar") into inches?
par("mai") could help, but does not (see code below).

space to the plot width&height, everything is in cm):
pdf("test.pdf",width=(20+2+4)/2.54,height=(10+3+1)/2.54)

circular reference lines in splom
Hello everyone,
I'm stumped. I'd like to create a scatterplot matrix with circular
reference lines. Here is an example in 2d:

colnames(dat) <- c("X1", "X2", "X3")
dat <- as.data.frame(dat)

Correlograms and linear regression
Dear all,
I generated a Correlograms and used the panel.ellipse (confidence ellipse
and smoothed line) option. Is there a way to get instead of the smoothed
line the linear regression?
Thanks,

masking functions
Dear all
I was writing some code that needed functions from packages 'MASS' and
'CircStats', and I received a warning saying that the function
'eqscplot' in one of the packages was masked by another 'eqscplot' from
the other package (in fact 'eqscplot' from 'CircStats' seems a short
version of 'eqscplot' from 'MASS'). This masking of

density ellipses?
Hello,
has anybody written a function to plot density ellipses (95%, 99% or
anything) in a scatterplot? I found nothing in any package, nor in the list
archives.
There does seem to be a contributed package "ellipse" for S-Plus (on
S-Archive), but it does a lot more than what I would need. Still, if anybody
ported it to R, I'd be grateful for a link. I'm a bit afraid to try the
