det {base} | R Documentation |
det
calculates the determinant of a matrix. determinant
is a generic function that returns separately the modulus of the determinant,
optionally on the logarithm scale, and the sign of the determinant.

The determinant
function
uses an LU decomposition and the det
function is simply a
wrapper around a call to determinant
.
Often, computing the determinant is not what you should be doing to solve a given problem.
