PAM Clustering
Dear Germano,
Thank you for your fast reply,
In the above code, *MYData *is the actual data set.
Do not we need to convert *MYData to *the dissimilarity matrix using
*pam(as.dist(**MYData**), k = 10, diss = TRUE*)* code line?*
*Regards.*

PAM Clustering
Sorry, I never use pam. In the help, you can see that pam require a
dataframe OR a dissimilarity matrix. If diss=FALSE then "euclidean" was use.So,
I interpret that a matrix of dissimilarity is generated automatically.
Problems may be in your data. Indeed
pam(ruspini, 4)$diss
write a dissimilaty matrix
while
pam(MYdata,10)$diss

Dear Authorized Sir / Madam,
I have an R script file in which it includes PAM Clustering codes:
*when i ran R script i am getting this error:*
*Error in pam(d, 10) : x is not a numeric dataframe or matrix.*

cross-validation for count data
Hi everybody,
I'm trying to use cross-validation (cv.glm) for count data. Does someone know which is the appropriate cost function for Poisson distribution?
Thank you in advance.

Rpart - best split selection for class method and Gini splitting index
Dear R-users,
I'm working with the Rpart package and trying to understand how the
procedure select the best split in the case the method "class" and the
splitting index "Gini" are used. In particular I'd like to have look to the
source code that works out the best split for un unordered predictor.
Does anyone can suggest me which functions in the sources I should

em algorithm mixture of multivariate normals
Hi,
I would like to know if it is possible to have a "R code" to estimate the
parameters of a mixture of bivariate (or multivariate) normals via EM
Algorithm. I tried to write it, but in the estimation of the matrix of
variance and covariance, i have some problems. I generate two bidimensional
vectors both from different distribution with their own vector means and
variance and

problem with uniroot
Hi R-users,I'm trying to solve a non linear equation, to find the degrees of
freedom of a mixture of t student. I'm sure i wrote the minimization
equation in the right way, but when i try to run the EM algorithm to
estimate the parameters of the mixture, the following error will appear:

exporting clustering results to table
Hello list,
the following approach did not work:

gc();
filenameclu = paste("filenameclu", ".txt");
write.table(clustersA , file=filenameclu,sep=",");
although it worked with
clustersA <- hclust(distances, method="ward");
and a consecutive

help on dirichlet distribution
Dear Gregory R. Warnes,
I'm a phd student in statistics, at the University of Milano Bicocca.
I'm interested to the methods of estimate the parameters of the Dirichlet distribution.
Do you have implemented an algorithm in R?
If so, can you give me the script? or, in general, some helps?
Best Regards

Spatio-temporal analysis of homicide rates
Dear R-listers,
I would like to carry out a very basic descriptive analysis of homicides
rates in Italy, taking into account both the spatial dimension (103
provinces) and the temporal dimension (10 years), but no covariates. In
practice, what I would like to do is to describe spatio-temporal variation
of homicide rates, identifying those combinations of province-year where

a question on the use of 'solve'
Dear R users,
I am in trouble using the function
solve(matrix)
in a loop.
When it happens that I have a singular matrix, I get an error message saying
so and the loop stops.
My question is if there in any way to keep on going in the loop.
Thank you in advance,
