Expecting a single value: [extent=0]

[LefterisZ]

Hello, I am getting the below error when updating RcppML from 0.3.7 to the current GitHub release.

The error arises when using either Rcpp_nmf_dense or Rcpp_nmf_sparse. It seems related to C++ since both functions are calling C++ code internally which I cannot figure out since my C++ knowledge is limited to non-existent!

I am using RcppML in one of my packages which will be published soon. Although I will revert to using the 0.3.7 version, where the error is not present, I would love to use and incorporate the latest version of RcppML with all the extra functionality it has!

I tried it even with a random 20x5 matrix:
A <- matrix(rnorm(100), ncol = 5, nrow = 20)

The Error:

<error/rlang_error>
Error:
! Expecting a single value: [extent=0].

The same problem

This problem occurred to me as well, when running
RcppML::nmf()
Try to load package RcppML and run nmf() function:

library("RcppML")
model <- nmf()

Don't know why?
