I am trying to teach myself a little R and recently I found an entry
over at R-Bloggers & Expansed, on how to create social graphs from your
email
<http://expansed.com/2011/08/sna-visualising-an-email-box-with-r/>, that
interested me.
I am using Mac OS Lion, so I installed the R-2.13.1pkg and the R.app
R-2.13-patched. The script requires the Network, rJython, and rJava
libraries, so I installed these as binaries. Mac OS Lion does not come
with a Java Development Kit installed, so I installed one from Mac Ports
and then I also tried building it from source based on the
instructions. I then registered the JDK with R using "sudo R CMD
javareconf". The script fails when executed with the following error:
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, :
Traceback (most recent call last):
File "<string>", line 1, in <module>
File
"/Library/Frameworks/R.framework/Versions/2.13/Resources/library/rJython/jython.jar/Lib/imaplib.py",
line 437, in fetch
File
"/Library/Frameworks/R.framework/Versions/2.13/Resources/library/rJython/jython.jar/Lib/imaplib.py",
line 1055, in _simple_command

line 892, in _command_complete
imaplib.error: FETCH command error: BAD ['Could not parse command']
I have tried many, many different things but I simply can not work out
how to make this work. As other people sound like they have run this,
it is a mystery to me. One of the things I have tried was trying the
same thing in a virtual instance of Linux running on my Mac and that
segfaults. Another is installing the rJava library as source, so that
it would be compiled on my machine. This fails due to R expecting a
different framework version. The error returned is:
checking whether JNI programs can be compiled... configure: error:
Cannot compile a simple JNI program. See config.log for details.
and checking the log I find:
Dyld Error Message:
Library not loaded:
/Library/Frameworks/R.framework/Versions/2.12/Resources/lib/libR.dylib
Referenced from: /Applications/R.app/Contents/MacOS/R
Reason: image not found
I am using Framework version 2.13, so I do not even have a directory for
version 2.12. The file "libR.dylib" is in the right place for 2.13 but
I do not know how to configure R.app to use a particular version of the
Framework. Or even if this is actually the root of the problem above.
If anyone has any suggestions I would appreciate it... or even if
someone could try the script Expansed published and see if it works for
them, I would appreciate that as well.
Thanks!
