Hi, All:
I created several plots in R and associated them with
tabbed notebook widget (created from the
example on the R tcl/tk page
http://www.sciviews.org/_rgui). The plot itself is
created by tkrplot.
What I'd llike to do is to save the current plot
associated with the active tab. I searched
online and couldn't get it done. Your help is well
appreciated!
I am attaching this example code from that website.
Basically, when I click tab "B",
I want to save the corresponding plot. I used
"CopytoClipboard" button. But it always
copies the last plot, ie. tab Z's plot.
I guess I need handle the imglist as a list, but it
didn't allow me to do.

nm[t])))

tn$env), sep=".")

assign(ID, tbw, envir = tn$env)

X <- t + (1:20)
plot(X)}, hscale= 1.5, vscale= 1.5)

}
copy.but <- tkbutton(tbw,text=paste("Copy to
Clipboard", nm[t]),command=CopyToClip)
tkpack(imglist)
tkpack(copy.but)
#list(tbw,fr,lb) # return all three in case you
need them later
}
tkbind(tt, "<Destroy>", function() tkdestroy(tn))
tkselect(tn, 0)
