I'm trying to run the first two lines of the gWidgetsRGtk2 examples but I cannot find glade libraries in CRAN . So gladeXMLNew() function fails. Is there anybody who could help ?
## This requires glade libraries to be installed before compiling RGtk2
options("guiToolkit"="RGtk2")
library(RGtk2)
library(gWidgets)
library(gWidgetsRGtk2)
gladeFile <- system.file("examples/t.test.glade",package="gWidgetsRGtk2")
GUI <- gladeXMLNew("t.test.glade")
Thank you in advance
