R Documentation

Select Items from a List

Description

Select item(s) from a character vector.

Usage

select.list(list, preselect = NULL, multiple = FALSE)

Arguments

list	character. A list of items.
preselect	a character vector of length one, or NULL. If non-null and if the string appears in the list, the item is selected initially.
multiple	logical: can more than one item be selected?

Details

This brings up a modal dialog box with a (scrollable) list of items, which can be selected by the mouse. If multiple is true, further items can be selected or deselected by holding the control key down whilst selecting, and shift-clicking can be used to select ranges.

Normal termination is via the OK button or by hitting Enter. The selection can be aborted via the Cancel button or pressing Escape.

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.

select.list(sort(.packages(all.available = TRUE)))
