Hi All,

I tried to install the package of Rgraphviz in the following two ways successfully:

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

install.packages(pkgs="C:/Progra~1/R/lib_download/Rgraphviz_1.24.0.zip", lib="C:/Progra~1/R/R-2.10.1/library", repos=NULL)

but when I loaded the package though library(Rgraphviz) or library("Rgraphviz"), and got the same error message below:

"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."

I think that it is the error in the package 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'

Could anyone help me to solve to problem?
Thank you very much for the help. Howard
