Hi,

in this i m sending what are all the code line I had been written and the
error where i got
sc1 = new STATCONNECTORSRVLib.StatConnector();
sc1.Init(R);
and error at

I have solved the problem. It seems that the \Sexpr{} sequence is processed
by R rather than latex. If you use:
Sweave(Sweave-test-1.Rnw, syntax=SweaveSyntaxNoweb)
When processing in R then this is handled in the appropriate way.

Allen,
I would suggest reading about the str() function. It's great for getting
inside model outputs and seeing how they are constructed so you can
extract all the specific calculations you want.
Its a bit fiddly to get used to but there are plenty of examples on this
forum.
Hope this

How do I simulate data with 100 points from a normal distribution with n=200,
mean (5,0), and Σ=matrix(1,0,0,0.1). After how do I plot the dataset and
include cluster centers found?

Here is one possible approach to get you started (this is not a final
answer):
x - seq(-3,3)
y - seq(-3,3)
z - outer(x,y, function(x,y,...) x^2 + y^2 )
tmp - contourLines(x,y,z)
contour(x,y,z, lty=0)
lapply(tmp,
This sounds rather like homework. If so, then talk to your instructor for
help.
Otherwise:
First you go to R Site Search at http://finzi.psych.upenn.edu/search.html
or to google.
Then you search for normal distribution.
Then you search for plot.
Then you search for cluster.
If you have

For matrices you can use kronecker:
kronecker(rep(1, 6), data.matrix(Xdf))

You did not provide any data, so I will take a guess at what it looks like:

though, thinking about it, i suppose if one could work out the 'best'
