model-based question-better readable version
It is going to be easy question to you. I've started to interest in model-based clustering.
Adrian E. Raftery "Recent Advances in Model-Based Clustering: Image Segmentation and Variable Selection" (www.stat.washington.edu/Raftery)showed that we can compare different classification methods using BIC
statistic. For diabetes dataset the best model is VVV model with 3 classes- for this

hi,
When I try to use the function coordProj {mclust}

to identify uncertainty, it errors and send this warning message:

What is mclust up to? Different clusters found if x and y interchanged
Hello All...
I gave a task to my students that involved using mclust to look for clusters
in some bivariate data of isotopes vs various mining locations. They
discovered something I didn?t expect; the data (called tur) is appended
below.
p <- qplot(x = dD, y = dCu65, data = tur, color = mine)
print(p) # simple bivariate plot of the data; looks fine
mod1 <- Mclust(tur[,2:3])

EM unsupervised clustering
Hi All,
I have a n x m matrix. The n rows are individuals, the m columns are variables.
The matrix is in itself a collection of 1s (if a variable is observed for an
individual), and 0s (is there is no observation).
Something like:
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 0 1 1 0 0
[2,] 1 0 1 1 0 0
[3,] 1 0 1 1 0 0
[4,] 0 1 0

mclust: modelNames("E") vs modelNames=("V")
Hi,
I'm trying to use the library mclust for gaussian mixture on a numeric
vector. The function Mclust(data,G=3) is working fine but the fitting is not
optimal and is using modelNames="E". When I'm trying
Mclust(data,G=3,modelName="V") I have the following message:

Subsets in mclust
Dear group,
I want to use the mclust package on large data, and therefore I want to use
a subset in the initial clustering phase. From help(mclust):
k: If `k' is specified, the hierarchical clustering phase will
use a sample of size `k' of the data in the initial
hierarchical clustering phase. The default is to use the
entire data set.

Problem with Mclust
Dear All,
I fear I am badly misunderstanding something fundamental about the
mclust package.
Please considered the dataset pasted at the end of the email (you can
also have a look at
http://dl.dropbox.com/u/5685598/dataedges.csv
).
Now, I would like to use the info on columns 1,2 and 4 to predict the
value in column 3.
However, when I run the script below (obg_mining_script.R), I get

Mclust node labels
Hi,
A quick question from a social scientist new to R -
how do I get coordProj / plot.Mclust to label the
nodes by row names? Using "identify" only gives me the
row numbers... Thanks.

Mclust help
Hi, quick question from a social scientist new to R:
how do I add labels/row names to the nodes in
coordProj / plot.Mclust plots? Apologies if this is a
silly question... Thanks.

hello,
i already include the error in blue color word.
i hope it can help you to understand my question.
if not burden you, please give me a guide how to correct the error or maybe you
can correct the coding cause error.
thank you.

mystery "158"
This is a simple problem, but a mystery to me.
I'm trying to grab $Family "Scelionidae" from one dataframe and put it into
another dataframe occupied with NA in $Family. The result is a "158" ends
up there instead of Scelionidae.
Simply put fam$Family[1] <- least$Family[1]
If I have made a mistake here, can somebody point it out. I've included

Your data frame fam contains factors. Turn it into character strings using
fam$Family = as.character(fam$Family)
and try again. It may be helpful if you read up on R's factors, see ?factor.

how to use plot.lda included in MASS package?
Hi there,
I am a master student in Denmark, and apply R to analyze the drug data.
I use the function 'lda' to obtain a linear discriminant object, and
then wish to use 'plot.lda' to do the plot on this object like below.
drug.lda <- lda(Inhibition ~ NET_CHARGE + PKA_1 + MW + MLOGP,
data = drug.class, method = "moment")

discriminant analysis
Hi,
I have done different discriminant function analysis of multivariat data. With the CV=True option I was not able to perform the predict() call. What do I have to do? Or is there no possibility at all? You also need the predicted values to produce a plot of the analysis, as far as I know.
Here my code:

Well, ?factor does not say anything about this behaviour (assigning numeric code instead of level of factor). And actually if you do assignment for whole vector the result is different (vector in data frame is changed to factor).
