Hi Ernest, Kasper and others from previous threads of installing
Rgraphviz...
As noted many times in different threads on this list, there are
always problems with Windows users being able to successfully install
and use Rgraphviz because of an outside program, Graphviz. I just
went through 2 recent threads (links below) after the R 2.9/BioC 2.4
releases, and I still don't have Rgraphviz loading completely without
errors (although I think it's functional). First of all, somewhere in
one of the threads, Kasper (I think) said he needed to getting around
to writing a vignette on how to install everything properly, which
would be nice to have in the Documentation section of the Rgraphviz
page:
http://www.bioconductor.org/packages/release/bioc/html/Rgraphviz.html
Instead, the text at the top says to see the README file, which is in
the source distribution (probably difficult for the average Windows
user to actually get this file!). The instructions in the README file
for using the Windows binary of Rgraphviz say to download the
Graphviz ***2.22.2*** binary file. However, this is not the correct
version, as indicated in the links below. I just tried the Graphviz
2.22.2, and got all the same errors documented before. Then I
followed Patrick's suggestion on 4/29/09 to use Graphviz 2.20
available from here:
http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1.
msi
So here are the step I went through:
1. No other Graphviz version installed on my computer, no C:\Program
Files\GraphvizX.XX\bin in my PATH, R not running.
2. Installed Graphviz 2.20 using the file from the link above.
3. Made sure C:\Program Files\Graphviz2.20\bin is in my PATH.
4. Started R, downloaded and installed Rgraphviz using:
> source("
http://bioconductor.org/biocLite.R")
> biocLite("Rgraphviz")
Now, according to everything I can find in the archives, this
*should* have worked. But when I try:
> library(Rgraphviz)
I still am getting a Windows error box that pops up. The top says "R
Console: Rgui.exe - Entry Point Not Found" and the text in the box
says "The procedure entry point g_intern_static_string could not be
located in the dynamic link library libglib-2.0-0.dll." However,
when I then click OK on this error box, Rgraphviz appears to finish
loading fine:
> library(Rgraphviz)

$build_version

I don't really use Rgraphviz, so I don't have any code to see if
works completely. I had gotten to this same point a couple of R
versions ago, which is where Ernest found my e-mail. I still think I
had the Windows error message, which I guess I just ignored as
everything I needed to do back then seemed to work. So, should I and
others continue to ignore it now if we get to this point? Anything
else to try?
Writing the "how to install" vignette would really come in handy!!!
Thanks,
Jenny
