get: Return the value of a named object
In nturaga/BiocGenerics: S4 generic functions for Bioconductor

Description Usage Arguments Details Value See Also Examples

Search for an object with a given name and return it.

NOTE: This man page is for the get and mget S4 generic functions defined in the BiocGenerics package. See ?base::get for the default methods (defined in the base package). Bioconductor packages can define specific methods for objects (list-like or environment-like) not supported by the default methods.

1 2	get(x, pos=-1, envir=as.environment(pos), mode="any", inherits=TRUE) mget(x, envir, mode="any", ifnotfound, inherits=FALSE)

x

For get: A variable name (or, more generally speaking, a key), given as a single string.

For mget: A vector of variable names (or keys).

envir

Where to look for the key(s). Typically a list-like or environment-like object.

pos, mode, inherits, ifnotfound

See ?base::get for a description of these arguments.

See ?base::get for details about the default methods.

For get: The value corresponding to the specified key.

For mget: The list of values corresponding to the specified keys. The returned list must have one element per key, and in the same order as in x.

See ?base::get for the value returned by the default methods.

base::get for the default get and mget methods.
showMethods for displaying a summary of the methods defined for a given generic function.
selectMethod for getting the definition of a specific method.
