as.qmatrix is not working with R version >= 4

[haneenih7]

Hello developers,

The "as.qmatrix" function in tess3r is not working in R version 4 and above (I tested it in R 3.5.2 and it worked fine)

as.qmatrix(q4)
Error in if (class(Q) != "matrix") Q <- as.matrix(Q) : 
  the condition has length > 1

This issue because there was a change in R 4.0.0 and above, matrix objects now also inherit from class "array"

class(qq4)
[1] "matrix" "array" 

It should be giving only "matrix" so the as.qmatrix function would work.

I wonder how to solve this issue? I think this should be solved by updating the as.qmatrix function in the package.

Thanks a lot!
