WName
(Package: tkWidgets) :
Accessors for Primitive Widget Objects
Currently primitive widget objects (pwidgets) are implemented as lists, but this will change. Users should only rely on these accessors functions, not the implementation.
Takes a path and returns a vector of string with the names of files and directories for the path. The directory names will have a system dependent path separator (e. g. / for Unix) appended.
argsWidget
(Package: tkWidgets) :
Functions to construct a widget that takes inputs from users
Given a argument list, the functions construct a widget to allow users to entry or select values for arguments defined by the names of the argument list.
eExplorer
(Package: tkWidgets) :
A widget that allows users to explore the example code and help
Given a valid package name as a character string, eExplorer collects all the example code from the "R-ex" directory from the R library for that package and then displays the names of the code examples in a list box. When a name in the list box is clicked, the corresponding code will be displayed and users are allowed to execute the code or view the help file for the function the example code is for.
This function provides the widget for users to go up and down a path and view the files. When files are selected and the "End" button is pressed, the function returns a vector of character strings with the full paths of the selected files.
