| unique {BiocGenerics} | R Documentation |
unique returns an object of the same class as x (typically
a vector-like, data-frame-like, or array-like object) but with duplicate
elements/rows removed.
NOTE: This man page is for the unique S4 generic function
defined in the BiocGenerics package.
See ?base::unique for the default method
(defined in the base package).
Bioconductor packages can define specific methods for objects
(typically vector-like or data-frame-like) not supported by the
default method.
unique(x, incomparables=FALSE, ...)
x |
A vector-like, data-frame-like, or array-like object. |
incomparables, ... |

See ?base::unique for the value returned by the
default method.
Specific methods defined in Bioconductor packages will typically return an object of the same class as the input object.
unique should always behave consistently with
BiocGenerics::duplicated.
base::unique for the default unique
method.
BiocGenerics::duplicated for determining
duplicate elements.
showMethods for displaying a summary of the
methods defined for a given generic function.
selectMethod for getting the definition of
a specific method.
unique,Rle-method in the S4Vectors package
for an example of a specific unique method (defined for
Rle objects).
