cannot print/save graphics.
Hi,
I'm running the latest version of R on a linux box.
plot() does produce a grahpics window. But is it
"normal" for that window to not respond to a left
or right mouse click?
What I'm really trying to do is the save the graphics
to a postscript file, but postscript() produces an "empty postscript
file".
Thanks,
Caren

lda() - again.
Hi.
I asked a question about lda() and got some answers. However, one
question remains (which is not independent of the earlier ones):
What output does lda() produce which I can use to compute the
posteriors? I know predict(lda())$posterior will give me precisely the
posteriors, but suppose I'd like to compute them myself, outside
of R.
So far, I have not been able to use

t-test or conf interval with known variance?
Hello,
Is there a built-in test in R for hypothesis testing with samples of
known variance?
For example, I've got a set of data, a mean to compare against, and a
known variance, and I want to determine the p-value for which I can
reject the null hypothesis (mu_1 = mu_0) and accept the alternative
(mu_1 > mu_0). I've found that JMP and Minitab can both do this (in
JMP, it's a

A strange behaviour in the graphical function "curve"
I thought the curve function was a very flexible way to draw functions. So I
could plot funtions like the following:
# I created a function to produce functions, for instance:
fp <- function(m,b) function(x) sin(x) + m*x + b
# So I can produce a function like this
ff <- fp(-0.08, 0.2)
ff(1.5)
# Is the same as executing
sin(1.5) - 0.08*1.5 + 0.2
# Let's plot this

negative binomial lmer
To whom it may concern:
I have a question about how to appropriately conduct an lmer analysis for negative binomially distributed data. I am using R 2.2.1 on a windows machine.
I am trying to conduct an analysis using lmer (for non-normally distributed data and both random and fixed effects) for negative binomially distributed data. To do this, I have been using maximum likelihood,

of dichotomous variables F1,F2,F3
mu prints out as k rows (one for each Xi) of 8 numbers

How to change the label in plot.ts ?
Hi you guys:
I have been wondering if there is any way to change the labeling in plot.ts( ), for example , if I plot two sequences,
i always got y labels as "series1", "series2", I tried to use ylab=c((expression(mu_1)),(expression(mu_2))), but it
doesn't work.
thanks in advance for any help

Contrasts and MC
Dear R People:
I have a few questions about multiple comparisons
and contrasts for ANOVA, please.
I've tried some things but with no success.
Suppose I have a completely randomized design,
and I want to have the contrast
\mu_1 - 0.5 \mu_2 - 0.5 \mu_2
How do I set that up, please?
I used the C command, and ran aov, but the results were identical to those
with no contrasts.

I don't understand - surely the limits should be applied in the *child*

Error in simulation. NAN
Hi all,
im triyng to implement a bayesian model with R and c++.
I have a strange problem. I can't reproduce the error with a small

The problem is after the line

For the first 34 iterations all work fine, after, all the simulations

Howto hide scsi or other hardware from the virtual system
Hi,
I have created a virtual system via xen and would like to strip some
unrequired virtual hardware from it.
Example: my virtual Windows system shows me a scsi PCI device (as
unknown device). I would like to get rid of it - I am only using IDE in
the virtual system.
How can I hide specific hardware from the virtual system?
Cheers,
Emre
