Hi Thomas,
Thanks for the contribution. Is your code released under a particular
license, or could it be incorporated in the main code base for rpy2 ?
I'd see few things to tweak (for example make the class a singleton to
prevent problems when calling several times rliveenvents.start() without
calling rliveevents.stop() in between), but that would be an helpful
addition.
Best,
Laurent

Hi all,
Working with rpy2, I ran into the "why isn't my graph updating when I
resize the window?" question. I found the answer in the rinterface
documentation
[http://rpy.sourceforge.net/rpy2/doc-2.1/html/rinterface.html#rinterface-interactive-processevents],
but I thought I could improve on it in a few ways:
- The updates thread outlives the main thread, and stops the
interpreter from exiting
- There's no obvious way to stop the updater when you no longer need it
- If it tries to call process_revents() while R is drawing a graph, it
hits a runtime error
I have a small module which seems to solve all of these problems, but
I think it would be better as part of rpy2, so that you could do
something like:
from rpy2 import robjects, rliveevents
# Do stuff
rliveevents.stop() # If you want to save performance
# Do more stuff
rliveevents.start() # Start processing events again
# Yet more stuff
# Thread will automatically stop on exit (daemon mode)
I've put the code here: http://pastebin.com/DPzJMCEV
Thanks,
Thomas
