Hi
I am having problems installing and loading Rgraphviz.
I have tried installing it in Windows with R versions 2.10.1 and
2.11.0, it appears to install ok but when I load it I get the
following error
Error : .onLoad failed in loadNamespace() for 'Rgraphviz', details:
call: value[[3L]](cond)
error: unable to load shared library
'C:/PROGRA~1/R/R-211~1.0/library/Rgraphviz/libs/Rgraphviz.dll':
LoadLibrary failure: The specified module could not be found.
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 have also tried installing it running R version 2.10.0 in Unix and I
get the following error
configure: No --with-graphviz option was specified. Trying to find
Graphviz using other methods.
checking for pkg-config... /usr/bin/pkg-config
Package libgvc was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgvc.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgvc' found
configure: pkg-config was not able to find the Graphviz library
libgvc. This either indicates that Graphviz is old or that something
is wrong. Verify Graphviz is installed and that PKG_CONFIG_PATH is
correct.
checking for dotneato-config... no
configure: dotneato-config not found in PATH.
configure: Using default directory /usr/local, consider specifiying
--with-graphviz
configure: error: /usr/local/bin/dot not found. Check Graphviz
installation.
ERROR: configuration failed for package 'Rgraphviz'
>From searching the various forum a lot of people appear to have had
problems installing Rgraphviz but I cannot find many solutions.
Can anyone help?
Thanks
Janet
