translating sas proc mixed to lme()
Hi All
I am trying to translate a proc mixed into a lme() syntax. It seems that I was
able to do it for part of the model, but a few things are still different.
It is a 2-level bivariate model (some call it a pseudo-3-level model).
PROC MIXED DATA=psdata.bivar COVTEST METHOD = ml;
CLASS cluster_ID individual_id variable_id ;
MODEL y = Dp Dq / SOLUTION NOINT;
RANDOM Dp Dq / SUBJECT = cluster_ID

Question about plot.mona {cluster}
Hello all, I what to print the banner plot that is output from the mona
method in the cluster package but the problem is I dont want to print all
that red ink. Here is an example:

I can change the bar color by using the argument col=c(0,0) -

ggplot2 argument handling odd
Hello there,
I'm trying to do lots of plots in one for-loop. But somehow ggplot does
not evaluate arguments as expected. Here is an example:
library(lattice)
library(ggplot2)
pl <- list()
pl2 <- list()
cDat <- as.data.frame(cbind(x1=0:100,x2=0:10,x3=1:20))
for(obs in c("x1", "x2")) {
pl[[obs]] <- xyplot(cDat[,obs] ~ cDat[,"x3"], main=obs)

CTDB+GFS2+CMAN. clean_start="0" or clean_start="1"?
Hi everybody,
I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not
understand some points.
It is possible to run the CTDB defining it under services section in
cluster.conf but running it on the second node shuts down the process at the
first one. My CTDB configuration implies 2 active-active nodes.
Does CTDB care if the node starts with clean_start="0" or

when virEventAddTimeout trigger timeout ,should in the callback call virConnectDomainEventDeregisterAny ?
hi, all
I do a hotplug detach a network in a thread, because virDomainDetachDeviceFlags maybe asynchronous, so I do like follow:

2-parameter MLE problems
Hi all,
Sorry for the re-post, I sent my previous e-mail before it was complete. I
am trying to model seroprevalence using the differential equation: dP/dt =
beta*seronegative*.001*(seropositive)-0.35*(0.999)*(seropositive)-r*seropositive.
I would like to estimate my two parameters, beta and r, using maximum
likelihood methods. I have included my code below:

location of key in panels of trellis plot
Hi,
I want to insert a key into each panel of a trellis plot, which I can do
with a custom panel function that calles draw.key. The problem arises
because I want the top right hand corner of the key to start in the top
right hand corner of the panel. If you run my code below, you can see that
the key appears in the center of each panel. This is because the default
viewport in draw.key is the

Scaling variables to positive values using scale() or performing BoxCox on negative data
Hi,
I'm doing some work with linear models, and I've scaled my data using the
scale(dataset) function. This was great at removing the skew, but I now
can't perform the Box Cox transformation on the data set (using the
boxcox(dataset) function), as the scaling has returned negative values.
So my question is: how can I get the scale function to return a positive set
of data (so I can

negative number to positive number
Hello all,
I know this is a pretty easy question but I can't find it in S poetry or
R help.
How can I make a negative number positive. Such as
-5 to be +5
I tried +(-5), but that didn't work.
So no, I don't mean taking a -5^2 just to get a positive number.
This is in a function so it's not just -5 it's x. :)
Thanks,
Paul

Relase positive with log and zero of negative with 0
This is a very simple question but I couldn't form a site search quesry that would return a reasonable result set.
Say I have a vector:
x <- c(0,2,3,4,5,-1,-2)
I want to replace all of the values in 'x' with the log of x. Naturally this runs into problems since some of the values are negative or zero. So how can I replace all of the positive elements of x with the log(x) and the

There is one question I have though. I can see that worksheets and history

Stacked bar plot anomaly When column contains a negative and a positive value
Hello users,
I've noticed a problem when creating a stacked column plot when a column
contains a negative and a positive value. e.g.
series1<-c(-1,-2, 3, 4, 5)
series2<-c( 5, -4,-3,-2, 1)
data<-rbind(series1,series2)
barplot(as.matrix(data), beside=FALSE)
In these cases (i.e. first, third and fifth columns) the plotting is not
handled correctly. Compare this output with that
