Sorry Gabor, you are right, using mar= alone is enough to do the stacking. I
was wrong.

To make the charts the same size, try setting the top and bottom
margins to be the same; e.g.,
layout(rbind(1,2))

One of the wonderful things about R/S is how easy it is to turn code into a new
function definition. Here is a function based on your code (with a couple of
small modifications):
col.sd.hist <- function(x, cols=c('red','blue','pink'), ...) {
xbar <- mean(x)
SD <- sd(x)
BR <- seq(xbar - 4*SD

Thanks Jim! It seems layout() is necessary in addition to mar=. I have a
follow up question: is there a way to specify the height of each chart so
that all the charts have the same height? I tried pin=, but it created more
space (if the height is set to a small value) between the charts, although

Hi,
I have the following jackknife code which is much slower than my colleagues C
code. Yet I like R very much and wonder how R experts would optimize this.
I think that the for (i in 1:N_B) part is bad because Rprof() said sum() is
called very often but I have no idea how to optimize it.

Hi,
I tried to stack two charts on top of each other using the following
R functions:
par(mfrow=c(2,1))
plot(rnorm(1:3),xaxt="n",xlab="")
plot(rnorm(1:3))
This created two charts, one on top of the other, but there is too much
space between them. Does anyone know how to elimiate the space in bet
Use this panel function:

I would like to put a number to each of the plotted curves in each

Hi, ZJ,
In verification package, there is a function that takes observed
response and predicted probability and then calculate the ROC.
I am not sure if it is what you are after.

John,
The key issue with a data set that has no events in one group is that the
usual Wald tests, i.e., beta/se(beta), do not work. They is based on a Taylor
series argument of the usual type: f(x) = f(x0) + a polynomial in (x-x0), and
for infinite beta "x" and "x0" are so far apart that the

The semantic gymnastics below aren't necessary (nor are necessarily they a
bad idea). This is basically FAQ 7.21. So, e.g.
z <- c("x1","x2")
mod <- lm(y ~ get(z[1]) + get(z[2]))

Thanks Rob,
Since I already had Xcode 3.0, I re-installed gfortran (from the R
website, not
from the .dmg) and gcc4.2.1 preview. I am afraid the outcome was the
same, i.e.
jags 1.0.1 not found.
Yes I do use Macports (and formery used Fink, which is still installed). What
issues does this raise?
Hi all,
I'm having this error, since I'm working with a data matrix I don't understand
what's happening; I've tried several ways to solve this, even working with

simple matrix 3*3 and still got the same error.

This _is_ Mac-specific, so please use R-sig-mac.
It looks like changing the time zone is changing the behaviour of the
system function strptime. But we need a reproducible example (see the
footer of this and every message). You can probably create one by
debugging the failing call and seeing

I've imported an spss-file using read.spss. One variable has value like
'Ärzte'. I thought this is UTF-8 encoded, but it is not
