R 3.5.0 fails its regression test suite on Linux/x86_64
Hi,
I just tried to upgrade Nixpkgs to R 3.5.0, but unfortunately the new
version fails its regression test suite. We configure the build using
the flags "--without-recommended-packages", in case that's relevant. You
can see a complete build log with all relevant information at [1].
Anyway, the test failures look like this:

Proper way to define cbind, rbind for s4 classes in package
Are you able to create a reproducible example, somehow?
Thanks,

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.

Proper way to define cbind, rbind for s4 classes in package
Hi all,
this question has already been posted on stackoverflow, however without
success, see also
http://stackoverflow.com/questions/27886535/proper-way-to-use-cbind-rbind-with-s4-classes-in-package.
I have written a package using S4 classes and would like to use the
functions rbind, cbind with these defined classes.
Since it does not seem to be possible to define rbind and cbind directly
as S4

cbind() & rbind() for S4 objects -- 'Matrix' package changes
As some of you may have seen / heard in the past,
it is not possible to make cbind() and rbind() into proper S4
generic functions, since their first formal argument is '...'.
[ BTW: S3-methods for these of course only dispatch on the first
argument which is also not really satisfactory in the context
of many possible matrix classes.]
For this reason, after quite some discussion on

recursion problem using do.call(rbind, list(..,<S4>,..))
This was originally a bug report about Matrix,
https://r-forge.r-project.org/tracker/?func=detail&atid=294&aid=6325&group_id=61
but the bug is rather a "design" bug in R, or a limitation.
This e-mail is a report of the status quo as I see it, and
call for comments, sugguests, help/hints for workarounds,
or even a suggestion for a programming task helping R core to

rbind for a list
Dear All,
I´m using the following code:
all1<-gg2[[1]][[1]]; for(i in 1:48){ all1 <- rbind(all1,gg2[[i]][[1]]) }
to create a new matrix that contains all the matrices in a list called gg2.
gg2 is a list that looks like
>> gg2
[[1]]
[[1]][[1]]
<matrix one>
[[2]]
[[2]][[1]]
<matrix two>
.
.
.
[[48]]
[[48]][[1]]
<matrix 48>
Is there a faster way to do the rbind?

package check fail on Windows-release only?
I mistakenly left a write in "/tmp" in the rockchalk package (version
1.8.109) that I uploaded last Friday. Kurt H wrote and asked me to fix
today.
While uploading a new one, I became aware of a problem I had not seen.
The version I uploaded last Friday, 1.8.109, has OK status on all
platforms except r-release-windows-ix86+x86_64. I get OK on
oldrel-windows and also on devel-windows.

buglet in weighted.residuals(mlmObject)
When weighted.residuals() is given a fitted model
object with several responses (class mlm) and some
zero weights it returns a vector instead of a matrix.
It looks like it is doing
resids[ weights != 0 ]
instead of
resids[ weights != 0, , drop=FALSE]
in the multi-response case.
E.g.,
> d4 <- data.frame(y1=1:4, y2=2^(0:3), wt=log(1:4),
fac=LETTERS[c(1,1,2,2)])

methods cbind2 bind_activation disrupts cbind everywhere
The methods package ?cbind2 includes the instruction to use via
methods:::bind_activation(TRUE). This changes the default definition of
cbind globally, disrupting proper evaluation in packages not using
cbind2. Is cbind2 a hold-over from a time when ... could not be used for
dispatch? What is a safe way for a package to use cbind2?
This came up in the context of complex package dependencies

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

Proper way to define cbind, rbind for s4 classes in package
Hi Michael,
I've tested your change in r67699 (using r67773) and the function now
correctly dispatches to r/cbind2 within the R-session without
bind_activation(TRUE). However, running unit tests using R CMD check I
figured out that the same function call delegates to r/cbind.matrix
(function uses S4 class as first- and matrix as second argument). Is
this a bug and/or how can I get function
