Is there a function in R to calculate the generalized determinant of a singular matrix? - similar to the ginv() used to compute the generalized inverse. I can't seem to find any R related posts at all.

[R] Moore-Penrose Generalized determinant?
If the matrix is singular, the determinant of the matrix and its M-P inverse are both zero.
