[BioC] [R] about the possible errors in Rgraphviz Package

[HU,ZHENGJUN]

Hi All,

  Sorry that it is unclear in the last email (see below), and I 
should say that:

I got the following error messages when I loaded the package 
through library("Rgraphviz") or library(Rgraphviz):

"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."

  Thanks, Howard
