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, ...)
A collection of the same mode as x that contains all elements
of x that are not present in y.
the first collection to consider.
the second collection to consider.
additional arguments passed to methods
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.
