[R] about the possible errors in Rgraphviz Package

[HU,ZHENGJUN]

Hi All,

  Before installing the Rgraphviz package successfully [e.g., 
source("http://bioconductor.org/biocLite.R"); 
biocLite("Rgraphviz")], (1) I downloaded graphviz-2.20.3.1.msi 
(also tried graphviz-2.26.3.msi) for MS Windows (XP) and installed 
it successfully and (2) I also installed the packages from 
bioconductor by: (Note: I use MS Windows XP and R 2.10.1 version)

source("http://www.bioconductor.org/biocLite.R")
biocLite()

  I got those error messages:

"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."

  Obviously, it seems it is the package problem because it should 
go to
'C:/PROGRA~1/R/R-2.10.1/library/Rgraphviz/libs/Rgraphviz.dll' 
instead of
'C:/PROGRA~1/R/R-210~1.1/library/Rgraphviz/libs/Rgraphviz.dll'

  Thank you for the reply. Howard
