R help - Aug 2013 - access the tcl history stream in tcltk

Hello,

Does anyone have a clue about how dump tcl's history stream out to a file
from R pointers to tcl? This should be accessible via
"tcl("history",...)
but the stream seems to be always empty.

library(tcltk) #Load tcltk
tcl("history","nextid") #should be 1, and it is
a1<-tclVar("1")
tclvalue(a1)<-2
tcl("history","nextid") #Should be 3, but alas, it is 1.
tcl("history","info")    #Sadly, tcl has no history
.Tcl("history nextid") #No joy here either.

Thanks, in advance, for any tips or clues.

Best,
Chris Marcum
