Dear all,
I am trying (without much success) to use the fuction 'silhouette'.
Would anyone encountered that before (or would know where I am wrong ?)
Please find below the R ouput. Thanks in advance,

locked environment and inheritance
Hi,
I have a S3 package with namespace called "myS3Pkg". Inside my package I would like to create
a S4 class which extends (adds 2 slots) another S4 class from some other package. The class
should be created in "myPkg" environment (and not global environment).
Using:

RFC: Matrix package: Matrix products (%*%, crossprod, tcrossprod) involving "nsparseMatrix" aka sparse pattern matrices
This is a Request For Comment, also BCCed to 390 package maintainers
of reverse dependencies of the Matrix package.
Most users and package authors working with our 'Matrix' package will
be using it for numerical computations, and so will be using
"dMatrix" (d : double precision) matrix objects M, and indirectly, e.g., for
M >= c will also use "lMatrix" (l: logical i.e. TRUE/FALSE/NA).
All the following is **not** affecting those numerical / logical
computations.

Matrix: How create a _row-oriented_ sparse Matrix (=dgRMatrix)?
..."dgRMatrix") :
> no method or default for coercing "dgTMatrix" to "dgRMatrix"
The general philosophy in 'Matrix' with all the class
hierarchies and the many specific classes has been to allow and
foster coercing to abstract super classes,
i.e, to "dMatrix" or "generalMatrix", "triangularMatrix", or
then "denseMatrix", "sparseMatrix", "CsparseMatrix" or
"RsparseMatrix", etc
So in the above as(*, "RsparseMatrix") should work always.
As a summary, in other words, for wha...

Matrix: How create a _row-oriented_ sparse Matrix (=dgRMatrix)?
Using the Matrix package, how can I create a row-oriented sparse
Matrix from scratch populated with some data? By default a
column-oriented one is created and I'm aware of the note that the
package is optimized for column-oriented ones, but I'm only interested
in using it for holding my sparse row-oriented data and doing basic
subsetting by rows (even using drop=FALSE).

operators as S4 methods
Dear all,
I need to re-define some mathematical operators (+, *, /, etc) for an S4
class based on array. All references I have found (S Programming, Green
Book) show how to define S3 methods for this (like in page 89 of S
Programming for "-.polynomial"). What is the preferred S4 way for doing
this? I hope I haven't missed some obvious piece of documentation.
Many thanks,

passing a matrix to C++ with .C()?
It seems that it is possible to pass a matrix to C++ by using .C()
The R part of the interface should be something like:
('C++function', matrix, numberRows, numberColumns )
...I guess.
The C++ part of the interface could be something like
void C++( double matrix[][], int numberRows, numberColumns )
but C++ requires to indicate the number of columns, that is, instead of
matrix[][], it
