[R-gui] Directing R output to a text window

You may run into some of the problems described by Luke 
Tierney's "Threading and GUI Issues for R" :
http://www.stat.uiowa.edu/~luke/R/thrgui/thrgui.pdf

But you can do something like this:

data(airquality)
txt <- capture.output(print.data.frame(airquality))

# See ?capture.output for more details.

library(tcltk)
tt <- tktoplevel()
txtWidget <- tktext(tt)
tkpack(txtWidget)
tkinsert(txtWidget,"end",paste(txt,collapse="\n"))

i.e. the output of print.data.frame(airquality) which would 
normally be directed to the R console is now directed into the 
text widget.

If the reason you don't want to use the R Console for output is 
that you are using Windows and you find that RGui "steals the 
focus" from Tcl/Tk, then you can solve this by selecting :
Edit, GUI Preferences, SDI (Single Document Interface mode),
then click Save to save your RGui configuration preferences 
and then restart R.

Regards,
James
