[R] RGtk2 drawing area as cairo device - no points

[François Rebaudo]

Thanks !
Just in case it could be of any help, this is what I have done for MS 
Windows users :

library(RGtk2)
library(cairoDevice)
win = gtkWindow(show = FALSE)
win$setDefaultSize(500, 500)
hbox<-gtkHBoxNew(homogeneous=FALSE, spacing=0)
if (Sys.info()[1]=="Windows"){
     png(filename="temp.png", width = 500, height = 500)
         layout(matrix(c(1,1,2,3),2,2,byrow=TRUE))
         par(mar=c(4,4,1,1))
         plot(1:10) #boxplot(1:10)
         plot(1:10)
         plot(1:10)
     dev.off()
     myPLOT<-gtkImage(filename= paste(getwd(),"/temp.png",sep=""))
     hbox$add(myPLOT)
     win$add(hbox)
     win$showAll()
} else {
     da = gtkDrawingArea()
     asCairoDevice(da)
     hbox$packStart(da, expand = TRUE, fill = TRUE, padding = 0)
     win$add(hbox)
     win$showAll()
     layout(matrix(c(1,1,2,3),2,2,byrow=TRUE))
     par(mar=c(4,4,1,1))
     plot(1:10) #boxplot(1:10)
     plot(1:10)
     plot(1:10)
}
