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."
Most likely the problem is that you haven't followed the installation
instructions. (They are pretty hard to find, but I think you can find
them on the Bioconductor site.) It is not enough to install the
Rgraphviz package, you also need to install Graphviz.

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
