`R/neuronlist_sets.R`

`setdiff.Rd`

Find the (asymmetric) difference between two collections of objects

```
setdiff(x, y, ...)
# S3 method for default
setdiff(x, y, ...)
# S3 method for neuronlist
setdiff(x, y, ...)
```

- x
the first collection to consider.

- y
the second collection to consider.

- ...
additional arguments passed to methods

A collection of the same mode as `x`

that contains all elements
of `x`

that are not present in `y`

.

Note that setdiff.default calls base::setdiff to ensure consistent behaviour for regular vectors.

As a convenience `setdiff.neuronlist`

allows `y`

, the second
collection, to be a character vector of names.
