rp.control {rpanel} | R Documentation |
This function creates a panel window into which rpanel widgets can be placed. It also returns, and can set up variables within, the rpanel object.
rp.control(title = "", size = NULL, panelname, realname, aschar = TRUE, ...)
title |
the title of the panel displayed in the banner. |
size |
a two-element numeric vector specifying width and height of the panel in pixels. If this argument is omitted the size of the panel will adapt to the subsequent addition of widgets. |
panelname |
the name of the panel at .GlobalEnv. If this is not assigned, then realname is taken. |
realname |
retained for backward compatibility. If this is not assigned, the realname is assigned automatically using rp.panelname. |
aschar |
if TRUE (default) the panel's name as a string is returned. If FALSE the panel list itself is returned. |
... |
additional arguments which are treated as variable initialisations and are stored within the returned rpanel object. For example inserting x=3 creates a variable x in the rpanel object with the value 3. |
Dependent on parameter ischar. If ischar is TRUE this is the string name of the panel if FALSE this is the list object which defines the panel.
