unique {BiocGenerics} | R Documentation |
unique
returns an object of the same class as x
(typically
a vector-like, data-frame-like, or array-like R 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 R object. |

See ?base::unique
for the value returned by the
default method.
Specific methods defined in other 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.
