Return the value of a named object

Description

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.

Usage

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

Arguments

Details

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

Value

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.
