[R-gui] After resizing a tkwidget, how do I get the size of the widget??

[Carlos Rendon]

This should help a little bit:

jpeg(fileName)
someFunctionThatDrawsTheGraph()
dev.off()

you can also use:

fileName<-tclvalue(tkgetSaveFile(initialfile=".jpg",filetypes="{{JPEG
File} {.jpeg .jpg}}"))

to get the name of the file to save.
