This allows you to make a static copy of a GGobiDisplay.
ggobi_display_save_picture(display=displays(ggobi_get())[[1]],
path="ggobi_display.png", filetype="png", plot.only = FALSE)
GGobiDisplay to save
path to save to
type of file to save
if TRUE, save only plot, otherwise save surrounding GUI elements as well
If you want to make publicaiton quality graphics, you should probably use the DescribeDisplay plugin and package. This will recreate a GGobiDisplay in R, and so can produce high-quality vector (eg. pdf) output. See http://www.ggobi.org/describe-display for more information
