No method or default for coercing “matrix” to “RsparseMatrix”

[garyzhubc]

at times I run into this type of error:

Error in methods::as(bma$tt, "RsparseMatrix") : 
  no method or default for coercing “matrix” to “RsparseMatrix”
Execution halted

[RAPLER]

Can you tell me in which function this occurs?

[garyzhubc]

It was when I'm converting regular matrix into sparse matrix

bma$tt <- methods::as(bma$tt, "RsparseMatrix")

In which function of the package?

It’s not part of the package, but an issue that I have in converting sparse matrix as required by the package. Sent from my iPhoneOn Mar 14, 2024, at 2:28 PM, Claude Boivin @.***> wrote: In which function of the package?

I have already run into this problem, although it was within the package. I solved this by adding the package "methods" in the imports of the DESCRIPTION file. If the problem arise in a function you have defined, you may need to add: @import methods see this page on stackoverflow website: https://stackoverflow.com/questions/36432248/error-in-asdata-transactions-no-method-or-default-for-coercing-data-to
