Under the AQUA interface for Mac OS X this brings up a modal dialog box with a (scrollable) list of items, which can be selected by the mouse.
Otherwise it displays a text list from which the user can choose by
number(s). The multiple = FALSE
case uses menu
.
Preselection is only supported for multiple = TRUE
, where it is
indicated by a "+"
preceding the item.
Value
A character vector of selected items. If multiple
is false and
no item was selected (or Cancel
was used), ""
is
returned. If multiple
is true and no item was selected (or
Cancel
was used) then a character vector of length 0 is returned.
