Tensor comparison and asymmetric comparison between two vectors

zzasym_compare.Rd

Tensor comparison and asymmetric comparison between two vectors.

Usage

.ocompare(x, y)

.asym_compare(x, y)

Arguments

x

y

Details

.ocompare (for "outer compare") returns a matrix whose (i,j)th element is TRUE if x[i] is identical to y[j], and FALSE otherwise.

.asym_compare calls .ocompare and iterprets its result asymmetrically. Elements of x that are not in y ae considered "new". Similarly, Elements of y that are not in x ae considered "removed". Elements that are in both are "common".

Todo: check if the above is correct or the other way round! !!!

Value

For .ocompare, a matrix as described in Details.

For .asym_compare a list with indices as follows.

i_new

new elements, indices in x of elements that are not in y.

i_removed

removed elements, indices in y of elements that are not in x.

i_common

common elements, indices in x of elements that are in both, x and y.
