Error in texi2dvi
Hello:
Changes in R seem to have broken the sos vignette, and I don't
know how to fix it. The build on R-forge,
"https://r-forge.r-project.org/R/?group_id=235&log=build_src&pkg=sos&flavor=patched",
ends as follows:
Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet, :
Running 'texi2dvi' on 'sos.tex' failed.

quasi-random vector according to an independent graph
Dear R-users,
Is anyone aware of any function/package for generating a random vector from
a joint distribution defined by an independent graph? Or I have to work it
out myself?
Thanks.

can't get names from vector in nlm calls
I've been trying to figure out how to get the names of the parameter vector
variables when inside the function that nlm calls to return the objective
function value:
knls <- function( theta, eqns, data, fitmethod="OLS", instr=NULL, S=NULL )
{
## print( names( theta ) ) # returns NULL
## get the values of the parameters
for( i in 1:length( theta ) )

documentation for survival5?
Dear R-Helpers:
What other references are there on the capabilities of the survival5
package other than the help files and the chapter on survival analysis
in every edition of Modern Applied Statistics with S? I'm thinking of
something like "An Introduction to Survival Analysis in R" with worked
examples that might complement or extend the chapter in MASS.
Thanks,
Spencer

Re: [R] Printing Lattice Graphs from Windows (PR#6948)
Hi, Duncan:
I just did "plot(1:2)" in Rgui.exe, and that copied fine as a
metafile into MS Word via the clipboard.
Then I exited and restarted Rterm.exe under ESS and tried it
again. This time, I got a blank image copied into MS Word. However,
after I modified the Lattice defaults via,
"trellis.par.set('background', list('white'));

Faraway's book titled "Practical Regression and Anova using R",
with full text available online at:
http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf
refers to a data set, stat500, which compares midterm and final
grades. It can be used to illustrate similar concepts.
A google search for faraway.zip will locate the actual data.

Re: [R] Printing Lattice Graphs from Windows (PR#6947)
I agree: It sounds like a bug, as you said, Irk, in that
Rgui.exe cannot copy a metafile to the clipboard, at least under MS
Windows 2000, 5.00.2195, Service Pack 3, even though Rterm.exe can.
Therefore, I'm including "r-bugs@biostat.ku.dk" in the list of addresses
to this email.

Wikipedia plots and tables?
Hello, All:
What facilities exist for plots and tables of data in the
standard MediaWiki software beyond the obvious standards?
The standard MediaWiki tables and graphics capabilities seem to
me to be rather clumsy, and I wonder if I'm missing some available
extensions?
The standard MediaWiki tables are described in a Wikipedia
article on "Help:Table".

Nested anovas
Hello,
Is anyone out there doing nested anovas? I'm familiar with the notation to designate the nesting in SAS but can't seem to find any for R. How can I specify the nesting levels?
Thanks,

Counterintuitive Simulation Results
I wonder if someone can help me understand some counterintuitive
simulation results. Below please find 12 lines of R code that
theoretically, to the best of my understanding, should produce
essentially a flat line with no discernable pattern. Instead, I see an
initial dramatic drop followed by a slow rise to an asymptote.
The simulation computes the mean of 20,000 simulated trajectories

variance of combinations of means - off topic
Hello, and please excuse this off-topic question, but I have not been
able to find an answer elsewhere. Consider a value Z that is calculated
using the product (or ratio) of two means X_mean and Y_mean:
Z=X_mean*Y_mean. More generally, Z=f(X_mean, Y_mean). The standard
error of Z will be a function of the standard errors of the means of X
and Y. I want to calculate this se of Z. Can someone

fractal dimension of an image
Hello, I have a problem that I think can be solved in R but I'm not sure
how to tie things together.
I have a digital image of a crystal growth in 2 dimensions. And my aim
is to calculate the fractal dimension of the crystal. I was planning to
use the box counting method.
So I need to read in the image in R (for which I can use the pixmap or
rimage packages) and then draw a grid over at a

Least square minimization (non-linear)
Hi all,
I think the last time i posted this topic i started on the wrong foot. Thnaks alot to everyone who responded.
i'm coding in R(first time) for a paper my colleague is publishing. i plotted a histogram for 6000 values.
I am told to plot experimental vs theoretical vlaues from the histogram and do a non linear least square curve minimization and compute the mean and sd of the new x

I never made any assumption athat anyone had any obligation to do anything
I just asked a question. If I was too vague, then i am sorry. I dont
expect anyone to help me, but I thought that it was ok to put the
question out there in case someone wanted to help me. I didnt expect
abject hostility for it. Human decency was the only thing I did expect.
If my question was a pain,badly formatted, or too juvinile, then i have
no problem being ignored.I asked a question

logLIk(lme(...))?
Hello, all:
I have a dataset with 2 groups. I want to estimate 2 means and 2
standard deviations. I naively think I should be able to use lme to do
that, e.g., lme(y~gp, random=y~1|gp, method='ML'). I think I should get
the same answer as from lm(y~1, ...) within each level of group. I can
get the same means, but I don't know how to extract the within-gp
