Description

Check if the dependencies required to open a GUI are installed, and if opening a GUI does not throw an error. Some code adapted from RGtk2's .onLoad function.

Usage

checkGUI(GUI = c("needed", "always", "never"))

Arguments

GUI

One of "needed", "always" or "never". If "needed", a new window is opened to inspect the movements only when the movements table is too big to be displayed in R's console. If "always", a graphical interface is always created when the possibility to invalidate events emerges. If "never", a graphical interface is never invoked. In this case, if the table to be displayed does not fit in R's console, a temporary file will be saved and the user will be prompted to open that file and examine it. Defaults to "needed".

Value

An updated GUI argument (character string)
