Provide Default Behavior for listSelect Helper Functions
The function listSelect takes two functions which define
how the type information and content of R objects will be shown on
the widget created by listSelect.
Functions stdType() and stdView() provide the default
behavior.
stdType(toCheck) stdView(toView)
toCheck, toView |
arbitrary R object. |
These functions can be viewed as exmaples of defining functions for
the typeFun and valueFun arguments of the
listSelect function.
stdType() returns a character string describing the type of the
R object.
