Updated for compatibility with R >4.0.0. Since R 4.0.0, matrices have two classes, "matrix" and "array", which leads to a "condition has length > 1" error when running `if (!class(expr.mat)=="dgCMatrix")`. The "inherits" or "is" functions should be used instead of "==" for checking the class (https://developer.r-project.org/Blog/public/2019/11/09/when-you-think-class.-think-again/index.html).
