The reason for the above behavior has been
a) efficiency. All the subassignment ( `[<-` ) methods for
"RsparseMatrix" objects (of which "dsRMatrix" is a special case)
are implemented via TsparseMatrix.
b) because of the general attitude that Csparse (and Tsparse to
some extent) are well supported in Matrix,
and e.g. further operations on Rsparse matrices would *again*
go via T* or C* s...

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).
Here is what I

selectMethod() can fail to find methods in situations of multiple dispatch
Fine with me as long as eliminating the inconveniences associated with it can be put on the roadmap. The alias instability and the fact that the user has no way to know if s/he should do ?`foo,numeric-method` or ?`foo,numeric,ANY-method` to find the method has been a long-standing problem.

R, AIX 64-bit builds - trying to understand root cause for message: "Error: Line starting 'Package: tools ...' is malformed!"
The bulk is on my forums - the final post for today is:
Results to date:
A. It looks like I am going to need a newer compiler for C - xlc/xlC V11
apparently does not understand this code:
"/data/prj/cran/R-3.2.3/src/main/memory.c", line 2149.31: 1506-046 (S)
Syntax error.
I will have to check if R-devel has different code before asking for
assistence.
