Thanks you Kriti for your answer.
I have tried both the CRAN and github versions and the problem is the same, as these operations are no longer supported, in fact I see that the only operation supported is the calculation of the covariance matrix, which in fact needs internally both the product and the sum of matrices, so I find this change of development strategy very strange.
The truth is that the integration with R at the level of linear algebra operators, as described in https://www.paradigm4.com/try_scidb/scidb-r/, was what interested me most about SciDb, if not the only thing.
It seems to me that it is a great loss to eliminate the operators of linear algebra in R, especially being something that apparently was working well.
I had planned to use the professional version of SciDB in the Azure cloud in a project that will start in a few days, but I’m afraid it’s not going to be possible, unless in the version for companies these operators are still maintained, and there are guarantees that it will continue to be so in the future.
I’m very sorry, but if not, I’m no longer interested in this product because it was an indispensable condition to be able to use it in my work environment.
