Hi,

I ran into a curious edge case, where summing a ConstantArray with a vector fails if both are zero and then writing it with HDF5Array::writeHDF5Array, but not in any other combination:

mat<-DelayedArray::ConstantArray(c(2, 4), value=0)
res<-mat+ rep(0, 2)
res#> <2 x 4> sparse DelayedMatrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 0 0 0 0#> [2,] 0 0 0 0HDF5Array::writeHDF5Array(res)
#> Error in .Arith_SVT1_v2(.Generic, e1, e2): "+" is not supported between a SparseArray object and a numeric vector#> (result wouldn't be sparse in general)# All other combination seems to workmat<-DelayedArray::ConstantArray(c(2, 4), value=0)
res<-mat+ rep(3, 2)
HDF5Array::writeHDF5Array(res)
#> <2 x 4> HDF5Matrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 3 3 3 3#> [2,] 3 3 3 3mat<-DelayedArray::ConstantArray(c(2, 4), value=17)
res<-mat+ rep(0, 2)
HDF5Array::writeHDF5Array(res)
#> <2 x 4> HDF5Matrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 17 17 17 17#> [2,] 17 17 17 17mat<-DelayedArray::ConstantArray(c(2, 4), value=0)
res<-mat+0HDF5Array::writeHDF5Array(res)
#> <2 x 4> sparse HDF5Matrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 0 0 0 0#> [2,] 0 0 0 0

Created on 2025-03-05 with reprex v2.1.1

I am not actually 100% this is an DelayedArray issue or if it might rather need to be moved to HDF5Array.

Best,
Constantin

              Hi,
              I ran into a curious edge case, where summing a ConstantArray with a vector fails if both are zero and then writing it with HDF5Array::writeHDF5Array, but not in any other combination:
              mat<-DelayedArray::ConstantArray(c(2, 4), value=0)
res<-mat+ rep(0, 2)
res#> <2 x 4> sparse DelayedMatrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 0 0 0 0#> [2,] 0 0 0 0HDF5Array::writeHDF5Array(res)
#> Error in .Arith_SVT1_v2(.Generic, e1, e2): "+" is not supported between a SparseArray object and a numeric vector#> (result wouldn't be sparse in general)# All other combination seems to workmat<-DelayedArray::ConstantArray(c(2, 4), value=0)
res<-mat+ rep(3, 2)
HDF5Array::writeHDF5Array(res)
#> <2 x 4> HDF5Matrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 3 3 3 3#> [2,] 3 3 3 3mat<-DelayedArray::ConstantArray(c(2, 4), value=17)
res<-mat+ rep(0, 2)
HDF5Array::writeHDF5Array(res)
#> <2 x 4> HDF5Matrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 17 17 17 17#> [2,] 17 17 17 17mat<-DelayedArray::ConstantArray(c(2, 4), value=0)
res<-mat+0HDF5Array::writeHDF5Array(res)
#> <2 x 4> sparse HDF5Matrix object of type "double":#> [,1] [,2] [,3] [,4]#> [1,] 0 0 0 0#> [2,] 0 0 0 0
              Created on 2025-03-05 with reprex v2.1.1
              I am not actually 100% this is an DelayedArray issue or if it might rather need to be moved to HDF5Array.
              Best,
