append: Append elements to a vector-like object

In nturaga/BiocGenerics: S4 generic functions for Bioconductor

Description

Append (or insert) elements to (in) a vector-like object.

NOTE: This man page is for the append S4 generic function defined in the BiocGenerics package. See ?base::append 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.

Usage

append(x, values, after=length(x))

Arguments

x	The vector-like object to be modified.
values	The vector-like object containing the values to be appended to x. values would typically be of the same class as x, but not necessarily.
after	A subscript, after which the values are to be appended.

Value

See ?base::append for the value returned by the default method.

Specific methods defined in Bioconductor packages will typically return an object of the same class as x and of length length(x) + length(values).

Examples

showMethods("append")
selectMethod("append", c("ANY", "ANY"))  # the default method
