## Tensor comparison and asymmetric comparison between two vectors

### Description

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`.
