tk_select.list {tcltk}R Documentation

Select Items from a List


Select item(s) from a character vector using a Tk listbox.


tk_select.list(list, preselect = NULL, multiple = FALSE, title = NULL)


list character. A list of items.
preselect a character vector, or NULL. If non-null and if the string(s) appear in the list, the item(s) are selected initially.
multiple logical: can more than one item be selected?
title optional character string for window title.


This is a version of select.list implemented as a Tk list box plus OK and Cancel buttons. There will be a scrollbar if the list is too long to fit comfortably on the screen.

The dialog box is modal, so a selection must be made or cancelled before the R session can proceed.


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.
