Hello,
Is it intended that is.vector(...) and is(..., "vector")

is.vector() works as documented ('is.vector' returns
'FALSE' if 'x' has any attributes except names.)
Thus,
A <- array(1:2, 1:2)

is.vector(M) # FALSE, as documented

Hello,
does adding the line

to the Rd-file of your "matrix.diag.csr" class solve the mysterium?

maybe, the point is that is.vector "attempts to coerce its argument into a
vector", but here it fails
is.matrix(as.vector(x1mat))
[1] TRUE

I think, it must be x instead of object?

Hi,
I found the following on Windows 2000/NT
R Version 1.9.1 (2004-06-21) (also Version 1.9.0):
The S4 group "Math" doesn't work as documented; i.e., "log", "log10",
"gamma" and "lgamma" are included
in the documentation but don't work. See example code below.
Moreover, what about 'genericForPr
Hi,
I'm working with Version 1.9.0 (2004-04-12) on Windows 98/NT/2000 where
I found the following wrong (?) behavior of setValidity().
I already mentioned this on the R-help list (2004-06-11, was
"setValidity changes Extends?") , but as I got no answer I tried to
figure out what's happening.

It is not at all clear to me what an 'AbscontDistribution' is. Perhaps you
are referring to a continuous distrib
