dialogMaker: Automatically create a dialog for a function

In traitr: An interface for creating GUIs modeled in part after traits UI module for python.

Description

Function must have a special markup for its argument. A named argument a..b is interpreted with b determining the type of item to use. We support numeric, string, choice, range, ??? Within the body of the function, the variable a..b should be referred to by a. The idea is that you write and debug the function as usual, then simply modify the argument list to include the types. This function will not work for functions whose arguments use lazy evaluation referring to other argument's values.

Usage

dialogMaker(f, title = "Dialog", help_string = "", make_gui = TRUE,
  add_graphic_device = FALSE, ...)

Arguments

f	function to make dialog for. Its arguments must be specified in a certain way.
title	Title for dialog window
help_string	String for help information
make_gui	If TRUE or add_graphic_device=TRUE then call dialogs make_gui method
add_graphic_device	If TRUE add an graphicDeviceItem to dialog
...	passed to make_gui when no graphic device asked for

Details

All arguments should have a default A choice items should have its default with a vector. The first argument is the selected one A range item is specified with values c(from=., to=..., by=..., [value=from]). If value not give, then from is used. The OK_handler will call f.

Value

Returns an instance of aDialog.

Examples

f <- function(x..numeric=1, y..string="a") print(list(x,y))
## Not run: dialogMaker(f)
## can have missing arguments
f <- function(x, y..numeric=1) print(list(x,y))
## Not run: dialogMaker(f)
## a choice item. Sizing is funny for tables
f <- function(x..choice=letters) print(x)
## Not run: dialogMaker(f)
## range items
f <- function(x..numeric=0, mu..numeric=0,
              alternative..choice=c("two.sided","less","greater"),
              conf.level..range=c(.80,1.00, .01, .95)) {
              out <- capture.output(t.test(x, alt=alternative, conf.level=conf.level))
              print(out)
}
## Not run: dialogMaker(f, title="CI from t.test with summarized values")
