BiocGenerics (version 0.18.0)

get: Return the value of a named object


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.


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


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).

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.


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.


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