Hola,
Aquí puedes encontrar una descripción de cómo solucionar el problema que
encuentras:
http://permalink.gmane.org/gmane.science.biology.informatics.conductor/32589
Básicamente, la parte en la que tienes que fijarte es esta:
and then add the path to the ''bin'' directory of the
installation to your
system''s PATH variable (Control Panels -> System -> Advanced
Settings ->
Environment Variables, then ''new'' or ''edit''
a user variable to be named
PATH as a semi-colon separated list of directory paths. When I did this
and restarted R, I saw in part
> Sys.getenv("PATH")
"<...>;C:\\Program Files (x86)\\Graphviz2.20\\bin;<...>"
where <...> are other paths not relevant to Rgraphviz, the the path that
I have might differ from the path that you have. To ensure that I had
entered the right PATH, I then did
> list.files("C:\\Program Files (x86)\\Graphviz2.20\\bin")
[1] "acyclic.exe" "bcomps.exe"
[3] "ccomps.exe" "circo.exe"
[5] "comdlg32.ocx" "diffimg.exe"
[7] "dijkstra.exe" "dot.exe"
[9] "dot2gxl.exe" "dotty.exe"
Saludos,
Carlos Ortega
