showMethods
Show All Methods for the Specified Function
Description
Shows all the methods for the specified function(s).
Usage
showMethods(f = character(), where = topenv(parent.frame()),
classes = NULL, includeDefs = FALSE, inherited = !includeDefs,
showEmpty, printTo = stdout(), fdef = getGeneric(f, where = where))
Arguments
| f |
a character vector specifying the names of one of more generic functions,
or a single generic function.
If it is missing, all generic functions that match the other arguments are used.
|
| where |
the environment to search to find generic function(s).
Supply either an environment or a number representing its position in the search path.
|
| classes |
a vector of class names.
If given, only methods whose signatures include one or more of these classes are printed.
|
| includeDefs |
a logical value.
If TRUE, the definition of the method(s) are printed along with the names.
The default is FALSE.
|
| inherited |
this argument is unimplemented. If given, it generates a warning.
|
| showEmpty |
this argument is unimplemented. If given, it generates a warning.
|
| printTo |
this argument is unimplemented. If given, it generates a warning.
|
| fdef |
the generic function definition to use.
|
Details
This function prints information about the methods for the specified generic functions, possibly
restricted to methods involving specified classes and other criteria determined by the various
arguments. If more than one generic function is specified, this function is called
for each generic function.
Value
returns NULL, invisibly.
