[R] about the possible errors in Rgraphviz Package

[HU,ZHENGJUN]

Hi Martin,

  I uninstalled graphviz-2.26.3.msi and then installed 
graphviz-2.20.3.1.msi. Then installed the
Rgraphviz package again. As expected, I got the same error 
messages as before:

"Error in inDL(x, as.logical(local), as.logical(now), ...) :
  unable to load shared library 
'C:/PROGRA~1/R/R-210~1.1/library/Rgraphviz/libs/Rgraphviz.dll':
  LoadLibrary failure:  The specified module could not be found."

  Thank you.
  Howard
