Two working examples, tested on DOS console and IDLE.
#test1.py
#r gui in a separate thread with processevents
from rpy2 import robjects
from rpy2 import rinterface
import thread
def refresh():
while True:
rinterface.process_revents()
time.sleep(0.1)
def plot():
robjects.r.plot([1,2,3,4],[1,2,3,4])
refresh()
thread.start_new_thread(plot,())
Run this code with "python -i test1.py".
#test2.py
#r gui and process events all in the main thread
from rpy2 import robjects
from rpy2 import rinterface
import thread
def refresh():
while True:
rinterface.process_revents()
time.sleep(0.1)
def plot():
robjects.r.plot([1,2,3,4],[1,2,3,4])
plot()
refresh()
If you want to get interactive inputs, you need to make a thread for
input and handle that from a main event loop (with a Queue or
something).
