[R] Saving Mean Relative Difference from all.equal()

Hello, Does anyone know how to save the numeric value of the "mean relative difference" when using the all.equal() command? For example this: all.equal(cov2cor(ITEMCOV),cor(item.data)) Gives: [1] "Attributes: < Length mismatch: comparison on first 1 components >" [2] "Mean relative difference
