Ravi -- Likely you need to
o. install graphviz ***2.16*** Windows ***binary*** distribution from
say, in dir $DIR. We use the following as an example:
If you install it in other dir, just use your dir correspondingly.
o. set the following Windows environment variables accordingly
(control panel -> systems -> Advanced -> Environment Variables ):
(a) create new user variables:
GRAPHVIZ_INSTALL_DIR (e.g., C:\/R-tools\/graphviz-2.16)
GRAPHVIZ_INSTALL_MAJOR (e.g., 2)
GRAPHVIZ_INSTALL_MINOR (e.g., 16)
Notice the way "\/" are used for the paths above.
(b) add to user variable 'path': $GRAPHVIZ_INSTALL_DIR/bin
This is from the instructions in the README file of Rgraphviz. Some
functionality remains unavalable, especially exporting to .dot files.
