append: Append elements to a vector-like object
In BiocGenerics: S4 generic functions used in Bioconductor

Description Usage Arguments Value See Also Examples

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.

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

`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.

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).

base::append for the default append method.
showMethods for displaying a summary of the methods defined for a given generic function.
selectMethod for getting the definition of a specific method.
append,Vector,Vector-method in the S4Vectors package for an example of a specific append method (defined for Vector objects).
BiocGenerics for a summary of all the generics defined in the BiocGenerics package.
