Hello,
I'm getting the same error others have gotten with Rgraphviz (v
1.27.0), but the previously posted solutions don't seem to be working:
> library(Rgraphviz)
Error : .onLoad failed in loadNamespace() for 'Rgraphviz', details:
call: value[[3L]](cond)
error: unable to load shared object
'C:/Users/ckingsley.TGEN/Documents/R/win-
library/2.13/Rgraphviz/libs/x64/Rgraphviz.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
Check that (1) graphviz is installed on your system; (2) the
installed version of graphviz matches '2.20.3'; this is the version
used to build this Rgraphviz package; (3) graphviz is accessible to R,
e.g., the
path to the graphviz 'bin' directory is in the system 'PATH'
variable. See additional instructions in the 'README' file of the
Rgraphviz 'source' distribution, available at
http://bioconductor.org/packages/release/bioc/html/Rgraphviz.html

Error: package/namespace load failed for 'Rgraphviz'
I have installed graphviz 2.20.3.1 and the PATH environmental variable
contains the path to the bin directory:
> grep("Graphviz", strsplit(Sys.getenv("PATH"), ";")[[1]], value=T)
[1] "C:\\Program Files
(x86)\\Graphviz2.20\\bin<file: \\graphviz2.20\bin="">"
> list.files("C:\\Program Files
(x86)\\Graphviz2.20\\bin<file: \\graphviz2.20\bin="">")
[1] "acyclic.exe" "bcomps.exe"
"ccomps.exe" "circo.exe"
"comdlg32.ocx" "diffimg.exe"
"dijkstra.exe"

"dotty.exe" "fc-cache.exe" "fc-

"GVedit.exe" "gvpack.exe"
"gvpr.exe"
[22] "GVUI.exe" "gxl2dot.exe"
"gxl2gv.exe" "iconv.dll"
"intl.dll" "jpeg62.dll"

"libcgraph-4.dll" "libexpat.dll"

"prune.exe" "sccmap.exe"

And the Rgraphviz.dll is present in the correct directory:
> list.files("C:/Users/ckingsley.TGEN/Documents/R/win-
library/2.13/Rgraphviz/libs/x64/")
[1] "Rgraphviz.dll"
I'm running 64 bit R 2.13.0 on Windows 7 Professional x64.
Thanks in advance.
