Madame,
I've read your answer for using R from Java, you've sais:
one is to use R in batch mode ie you create a file in your java code
with all the R commands and send it to R (via Process
pc=Runtime.getRuntime().exec(Rcall); )and then R creates an outputfile
with all the results.

All,
Happy World Cup and Wimbledon. This morning finds me with the first
of my many daily questions.
I am running a ks.test on residuals obtained from a regression model.
I use this code:
ks.test(Year5.lm$residuals,pnorm)
and obtain this output
One-sample Kolmogorov-Smirnov test
Without a self-contained example, it's difficult to say for sure.
However, this looks to me like false convergence: garchFit uses a
nonlinear iteration to try to maximize the likelihood by minimizing
(-log(likelihood)). The matrix of second partial derivatives of
(-log(likelihood))
The apparent contradiction here is again a case of inadequate
documentation and checking.
Because the order of the triplets in the triplet form of a sparse
matrix is essentially random it is permissible to have repeated
indices. As you have seen, the interpretation of repeated indices is
that

basename() works. If you're on a system that doesn't think \\ is a path
separator, you could do something like
x - C:\\Documents and Settings\\myName\\My
Documents\\RProjects\\Project1\\file.name.csv
basename(gsub('','/',x))

You do realize that Mahalanobis distance is just Euclidean distance on
some linear transformation of the variables? So all you need to do is to
transform the data you pass to kmeans to 'sphere' the Mahalanobis
distance.
The K means *algorithms* do depend on Euclidean distance (e.g. in
