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

[Scott Colwell]

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: 0.01523708"   

I'd like to save the value 0.01523708 in a numeric format.

Thanks,
