Dear all,
on my Windows XP R 2.4.0 version with Package its version 1.1.4 I have a
problem with
str() applied on an its-object after a simple matrix manipulation on the its
object (see below).
I am not sure, whether this a problem with my application, its or str().
Of course, one can make
> str(core(its(mat)) / 1)
num [1:2, 1:3] 1 2 3 4 5 6
- attr(*, "dimnames")=List of 2
..$ : chr [1:2] "2003-01-01" "2003-01-04"
..$ : chr [1:3] "a" "b" "c"
But its object should be able to handle simple matrix multiplications, even if
the result is a matrix.
Any help is greatly appreciated.
Many thanks in advance,
Stefan
