[R] any way to set X11() device geometry (screen offsets)?

I have already messed around with this for a few hours.  I have listed the
functions I wrote below.

The actual usage would look like this:

ids <- get.win.ids()

That xwit sure is useful!

get.win.ids <- function(){
   dl <- as.vector(dev.list())
   cur <- as.vector(dev.cur())
   ids <- c("")
   for (i in 1:length(dl)){
      if (cur==dl[i]){
         name <- paste("R Graphics: Device ",cur," (ACTIVE)",sep="")
      else {
         name <- paste("R Graphics: Device ",dl[i]," (inactive)",sep="")
      x <- strsplit(
         system(paste("xwininfo -name \"",name,"\" | grep \"Window
         split=" "
      ids[i] <- x[[1]][4]

resize.plot.win <- function(id,w,h){
   system(paste("xwit -id ",id," -resize ",w," ",h,sep=""))

move.plot.win <- function(id,x,y){
   system(paste("xwit -id ",id," -move ",x," ",y,sep=""))

dev.list() gives the list of current device numbers and dev.cur() gives
which one is "ACTIVE"

R> l<-dev.list()
R> act<-paste(l,"(inactive)")
R> act[match(dev.cur(),l)]<-paste(dev.cur(),"(ACTIVE)")
R> paste("R Graphics Device:",act)
[1] "R Graphics Device: 2 (inactive)" "R Graphics Device: 3 (ACTIVE)"
