NOTE: This man page is for the duplicated and anyDuplicated
S4 generic functions defined in the BiocGenerics package.
See ?base::duplicated for the default methods
(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.
duplicated(x, incomparables=FALSE, ...)
anyDuplicated(x, incomparables=FALSE, ...)?base::duplicated for a description of
these arguments.
duplicated method (see
?base::duplicated) returns a logical vector
of length N where N is:
length(x) when x is a vector;
nrow(x) when x is a data frame.
duplicated methods defined in Bioconductor
packages must also return a logical vector of the same length
as x when x is a vector-like object, and a logical
vector with one element for each row when x is a
data-frame-like object.The default anyDuplicated method (see
?base::duplicated) returns a single
non-negative integer and so must the specific anyDuplicated
methods defined in Bioconductor packages.anyDuplicated should always behave consistently with
duplicated.
base::duplicated for the default
duplicated and anyDuplicated methods.
showMethods for displaying a summary of the
methods defined for a given generic function.
selectMethod for getting the definition of
a specific method.
