[Rd] more Matrix weirdness

I think that this is because `[<-` dispatches on S4 methods only if the first
argument is S4.
?"[<-" says:

"These operators are also implicit S4 generics, but as primitives,
     S4 methods will be dispatched only on S4 objects ?x?."

   Am I being too optimistic in expecting this (mixing and matching 
matrices and Matrices) to work?  If x is a matrix and m is a Matrix, 
replacing a commensurately sized sub-matrix of x with m throws "number 
of items to replace is not a multiple of replacement length" ...

x <- matrix(0,nrow=3,ncol=10, dimnames=list(letters[1:3],LETTERS[1:10]))
rr <- c("a","b","c")
cc <- c("B","C","E")
m <- Matrix(matrix(1:9,3,3))
x[rr,cc] <- m

Hello,

R 4.0.2 on Ubuntu 20.04, sessionInfo() below.

I can reproduce this, sort of. The error I'm getting is different:


x[rr, cc] <- m
#Error in x[rr, cc] <- m : replacement has length zero

But if I check lengths and dimensions, they are identical().

identical(length(x[rr, cc]), length(m))
#[1] TRUE
identical(dim(x[rr, cc]), dim(m))
#[1] TRUE


What works is


x[rr, cc] <- as.matrix(m)

I ran Ben's code on RStudio 1.3.1073, the following is run with Rscript 
and the error message is the same.

For some reason this should hgave undergone manual inpection but got 
auto rejected. Ideally you would reduce the test timing so that the 
overall check time is less than 10 min .

I am unable to set break or use gdb with any success when I use that version.

On linux I would do R -d gdb but this gives "unknown option '-d'
"
while gdb R.exe (in the same directory as the debug version) gives the
same output as before.

I'm happy to help but I appreciate this list might not be the best
place to get a tutorial on using gdb on Windows.

Essentially, the steps are: build with DEBUG=T (to have debug symbols), 
possibly updating EOPTS in MkRules.local to disable optimizations, then 
run gdb loading RGui, "set solib-search-path", run RGui from gdb. Then
you can break to debugger from RGui menu, or just run the code that 
segfaults, and you get to gdb and can print the stacktrace, etc. You can 
find some information in rw-FAQ (R for Windows FAQ), but yes, it is 
harder than on Linux. We can take care of this report, but of course in 
the longer term it would help if more people could take their time to 
setup debugging and analyze bugs even on Windows.

Now fixed, the test needs to be run only on 64-bit builds where such 
long vectors/sequences are allowed.

[Rd] more Matrix weirdness

Yes, exactly,  very well found, Georgi!

This is something I would have wanted different for years,
exactly because of several such problems with the Matrix
package of which I'm the maintainer.

Long time ago I had also looked if I saw how to fix this
behavior inside 'methods' (i.e. the S4 infrastructure pkg)
and I think in this case also, inside R's basic C code.

At the time (~ 10 yrs ago) I gave up, but don't remember why.

I'm happy if you create a formal bug report, possibly "wishlist"
as it is documented behavior, for this infelicity...
and then I will probably add the  'HELPWANTED'  keyword.

Martin

I'm sorry Martin, but I don't understand your point here.

I'm assuming that you want the (S3) matrix, x, to be converted to an
(S4) Matrix.

However, this is not a question of method dispatch, as such.
But rather a question of type conversion (integer to numeric to complex, etc).

Specifically, can/should automatic type conversion, convert an S3 data
type to an S4 data type, even where user-defined data types are
involved?

[Rd] more Matrix weirdness

If the current semantics is to be kept, one approach might be to insert in the
internal code of "[<-" something like the equivalent of

If(isS4(value))
    value <- coreData(value)

with the contract that classes that wish to be treated as equivalent to basic
vector classes define suitable method for coreData(). So, a matrix class would
return a plain matrix, a vector class - a vector, etc. This is akin to
coredata() for time series in package 'zoo' and others.

Yes, exactly,  very well found, Georgi!

This is something I would have wanted different for years, exactly because of
several such problems with the Matrix package of which I'm the maintainer.

Long time ago I had also looked if I saw how to fix this behavior inside
'methods' (i.e. the S4 infrastructure pkg) and I think in this case
also, inside R's basic C code.

At the time (~ 10 yrs ago) I gave up, but don't remember why.

I'm happy if you create a formal bug report, possibly "wishlist"
as it is documented behavior, for this infelicity...
and then I will probably add the  'HELPWANTED'  keyword.

Martin
