Hello,
You're right, thanks.
In my solution, I had tried to keep to the op as much as possible. A
glance at it made me realize that one change only would do the job, and
that was it, no performance worries.
I particularly liked the interaction/droplevels trick.

a<-read.graph(file=file
Hello list,
Is anyone else having problems with read.xlsx? I used it on a project
at the end of last week, and now the same code is throwing an error:
dat=read.xlsx("data.xlsx",sheetIndex=1)
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, :
org.apache.poi.POIXMLExcepti
Not really answering your posed question, but
a) reshape2 uses dcast and acast
b) The "cast" step of "melt-cast-melt" can invoke plyr, and it seems like MCM
is just a very inefficient way for you to get at the plyr functionality.
Perhaps you should take a more direct route to your goal?

Just use 'predict' on the fitted model and subtract the predicted
values from the data.

see head(`?`, 20)
there is another funny thing: Sys.sleep(2 + rpois(1, 2)) (in theory R
can, although is unlikely to, sleep forever since it is a Poisson
distribution...)

No it's actually telling it to split by the two variables (variable, value)
if I understand your question correctly.
The confusion is my fault. I tend to be lazy when running examples and did
not rename the melt() output to something meaningful. I sometimes forget
that it's not just

Thanks for your answer! But I have to type 4 question marks and not 3
That's great :)

Looking at the gsl code suggest you can set environmant variables that
are used by configure, hence setting
GSL_CFLAGS = -I/data1/zhucai/local/gsl/include
GSL_LIBS = -L/data1/zhucai/local/gsl/lib -lgsl -lgslcblas
before R CMD INSTALL should do the trick (untested).

Dear phillen,
You can use the identify() command following boxplot() to identify outliers, or
more simply, the Boxplot() function in the car package, which will do this for
you (see the first example in ?Boxplot).
I hope this helps,

Probably the simplest answer is to google 'label boxplot outliers in R'. I
found half a dozen solutions, (one of them my own, but that doesn't quite
answer your question).
Adding names to a series of data can be as simple as saying
names(x) <- paste("x", 1:length(x))
After that, the solutions g

Dear Gian,
How contrasts are created by default is controlled by the contrasts option:

unordered ordered
"contr.treatment" "contr.poly"
So, unless you've changed this option, contr.poly() will be used to generate
orthogonal polynomial contrasts
PLEASE do read the posting guide.
You really need to supply some sample data and the code you are using. We can
make guesses about what you are doing but it is much easier to actually look at
the data and code.
Please use dput() ( see ?dput) to supply some sample data.

Hi,
I wanted to create a network of drugs that are being studied together.
So, I created a file as a graph.
But plot of my network is not corect!
It looks like to me that something else is lying behind this network links
created.
Could someone help me with this?
Thanx!

Hello,
I am interested in fitting a bilinear time series model in R after
determining its order for a given data.
Is there any command or function that I can use?
