Multidimensional contingency tables
How does one ideally handle and display multidimenstional contingency
tables in R v. 2.6.2?
E.g.:
> prob1<- data.frame(victim=c(rep('white',4),rep('black',4)),
+ perp=c(rep('white',2),rep('black',2),rep('white',2),rep('black',2)),
+ death=rep(c('yes','no'),4), count=c(19,132,11,52,0,9,6,97))

Register pressure calculation in the machine scheduler and live-through registers
Hello,
In a previous email, Matthias mentioned that register pressure estimates in the machine scheduler are not absolute; they only account for the registers that are used in the block.I assume that he meant that registers that are live-through (both live-in and live-out) are not accounted for in register pressure calculations. If a register is either live-in or live-out but not both, it must be

Perpendicular symbol in plotmath?
Hey,
Does anyone know of an equivalent to the LaTeX \perp (perpendicular)
symbol for adding to R plots? Parallel is easy enough ("||"), but I
haven't been
able to find a way of adding perpendicular. The plotmath documentation
doesn't mention how to do it, so I'm inclined to think that it doesn't
exist - but surely there must be some way of achieving the desired
result,

Draw a perpendicular line?
Hi,
I am trying to draw a perpendicular line from a point to two points.
Mathematically I know how to do it, but to program it, I encounter some
problem and hope can get help. Thanks.
I have points, A, B and C. I calculate the slope and intercept for line
drawn between A and B.
I am trying to check whether I can draw a perpendicular line from C to line
AB and get the x,y value for the point D

Many thanks to the moderator who pointed out errors and suggested the
correct information on this post. Over half the ideas are due to him. ;)
Don't forget this is about writing your own daemon or TCP program. Some
of the ideas here will not happen with today's software that has been
hardened. It is presented to prevent your software from being taken
advantage of.

Comparing multiple distributions
Hello eveybody,
I am studying the vertical distribution of plankton and want to study
its variations relatively to several factors (time of day, species,
water column structure etc.). So my data is special in that, at each
sampling site (each observation), I don't have *one* number, I have
*several* numbers (abundance of organisms in each depth bin, I sample
5 depth bins) which

ginv vs. solve
Why do
x<-b%*%ginv(A)
and
x<-solve(A,b)
give different results?. It seems that I am missing some basic feature of
matrix indexing.
e.g.:
A<-matrix(c(0,-4,4,0),nrow=2,ncol=2)
b<-c(-16,0)
x<-b%*%ginv(A);x
x<-solve(A,b);x
Thanks in advance,

Analisys in Multidimensional contingency tables
Dear R-list,
Hi everyone, Im trying to make an analysis of multidimensional contingency
tables using R. I' working with the Agresti example where you have the
data from 3 categories. The thing is how can I do the analisys using the
G2 statistics. Somebody can send me an Idea?
I attach the program where you can find the data.
Best Regards,

minimum distance between line segments
Dear R helpers,
I think that this may be a bit of a math question as the more I
consider it, the harder it seems. I am trying to come up with a way to
work out the minimum distance between line segments. For instance,
consider 20 random line segments:
x1 <- runif(20)
y1 <- runif(20)
x2 <- runif(20)
y2 <- runif(20)
plot(x1, y1, type = "n")
segments(x1, y1, x2, y2)

Can I scale the labels in a 'persp' graph?
Hi all:
I'm using 'persp' for 3D graphics.
I need the axis's labels smaller than by defect.
I see in 'help()', the information about 'par()'.
I have wrote:
>par(.....,cex.axis=0.5,cex.lab=0.5)
perspc(.................)
and the result don't change.
The question is: Can I change the size of labels in the perps graph??
Thank you in advance:

[LLVMdev] MI Scheduler Update (was Experimental Evaluation of the Schedulers in LLVM 3.3)

bsd-snprintf.c and NeXT.
I'm wonder if anyone happens to have a simplier (slower) version of
bsd-snprintf.c. It seems NeXT 3.3 (unsure about 4.2) is missing
mprotect().
If I could get something to replace that for a while and fix some of
theses utmp in login.c issues I may have a rough port NeXT to black
hardware.=)
Thanks

Strange Win Disk Size Info
Hi all,
I run Samba 3.0.28a-1ubuntu4.7 on a Ubuntu 8.04/x86_64 Xeon box. On
one huge XFS file system, I have several shares, which have XFS project
quotas applied. Looking at the file system info in Win (both 2k and
xp), I see a *very* strange size display (see screen shot).
Linux tells me about the folder hosting the share:

adding math(s) symbols to src/main/plotmath.c
I decided I wanted an "infinity" in some label text.
Many of these symbols should probably be incorporated in a different

[R-sig-Geo] Comparing spatial point patterns - Syrjala test
Hi,
I went ahead and implemented something. However:
- I cannot garantie it gives correct results since, unfortunately, the
data used in Syrjala 1996 is not published along with the paper. To
avoid mistakes, I started by coding things in a fast and simple way
and then tried to optimize the code. At least all versions given the
same results.
- As expected, the test is still quite slow
