Hi,
I have problem loading Rgraphviz. Following the instructions specified by the
README in Rgraphviz_1.20.3.tar.gz didn't help either.
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:\Graphviz-2.21) <--------------------------
I stated C:\Graphviz-2.21 (I also tried C:\/Graphviz-2.21)
GRAPHVIZ_INSTALL_MAJOR (e.g., 2) <--------------------------
I stated 2
GRAPHVIZ_INSTALL_MINOR (e.g., 20) <--------------------------
I stated 21
Notice the way "\/" are used for the paths above.
(b) add to user variable 'path': $GRAPHVIZ_INSTALL_DIR/bin
e.g., C:\Graphviz-2.21\bin <--------------------------
I stated C:\Graphviz-2.21\bin (I also tried C:\/Graphviz-2.21\/bin)
It should be 'PATH', not 'path': environment variables are case-sensitive
(in general, not sure what happens with PATH if set there).
library("Rgraphviz")
Error in inDL(x, as.logical(local), as.logical(now), ...) :

That does not mean Rgraphviz.dll: it means a dependent DLL. You did
actually install graphviz, I presume?
