Hello,
how does exactly the function looks like that estimates the parameters in SEM?
What methods are used?

I've been experimenting recently with the fantastic Sweave/xtable combination
for generating latex. In the xtable vignette, I found this great example of
printing a ts object by months.
Is there a way to modify this code to generate RED numbers inside xtable for
negative results in x.ts?

The function lme() is in the package nmle, ***not*** in lme4.
The somewhat analagous (but very different) function in lme4
is lmer().

Dear Kathie,
Try also:
t(sapply(zz, function(x) as.numeric( strsplit(x, "")[[1]] )))
If you want to delete the column names, then
res <- t(sapply(zz, function(x) as.numeric( strsplit(x, "")[[1]] )))
dimnames(res) <- NULL
res
should do it.

Dear Mark and the R list,
I apologise greatly for not having thanked you earlier for your help with
my last mail, which involved trying to sort out variance components using
two methods: a direct looped lmer, and a two-step analysis involving
regressions of AFLP markers on lmer residuals for
Dear all,
Is it possible to adjust the size of the cells in the heatmap generated by
R? I have a heatmap with many rows. Because of this, the size of the cells
is very small and the labels of the rows overlap. I have to shrink the
labels, but this makes them hardly readable. Any suggestions how I

Hi,
This is hopefully quite a straightforward quandary. I have made a simple R
plot but the values on my x-axis are sufficiently large enough that they
interfere my x-axis label. How can I shunt the x-axis label further away
from the x-axis?
Thanks

Yes this is working quite well. Basically, I am comparing data obtained from
GIS to data obtained from R. It's turning out that the latitude and
longitude values from GIS are not matching exactly those obtained in R, and

Hi Ron,
I'm not sure why ylab doesn't work. Maybe a bug. I note the label
doesn't get removed with labs() either. However using
scale_y_continuous(name="") does remove the label.
For the legend, you are using a fill scale, not a colour scale i.e.
fill=factor(dat[,2]), not colour=factor(da

Are you familiar with item response theory? You might consider functions
in ltm or MiscPsycho for dealing with binary response data.

Dear ALL,
In the Normal Linear Mixed Model (NLMM) we make the assumption that
the random effects are normally distributed. Is it possible to fit a
linear mixed model in R where the random effects are
assumed to have a Skew-Normal distribution? I am trying to reproduce
the results in the paper refe
Hi all, I was trying to draw a stacked density plot like that :
library(ggplot2); library(plyr)
dat <- cbind(rnorm(300), rep(c(1,2), each=150))
ggplot() + geom_density(aes(x=dat[,1], fill=factor(dat[,2]),
position="stack")) +
xlab("") + ylab("") +
scale_colour_manual(name = "
If you want to have a gui that allows you to change parameter values using
buttons/sliders/etc. and see what the effects are, then look at the tkexamp
function in the TeachingDemos package (see the examples on the help page).
If you have a predetermined set of values for the parameter of interes
You are probably going to get tons of answers, as there are many ways -- and
packages -- to do this (e.g. see packages reshape and plyr). However, you
might want to take a look at ?tapply, for which aggregate() is a wrapper,
for the basic core R approach.

Dear Adrian Dusa, others,
I've recently started to learn R in order to use the QCA package because
i think it might offer what other QCA packages don't: possibilities for
quite a few conditions and large n. However, can someone tell me approx.
how much RAM i need to run QCA on set of +/- 400.000
