Configuration :
Python 2.5.2
Windows Vista
R 2.7.0
I have been using rpy-1.0.3-R-2.7.0-win32 fine for quite some time and am
very happy with it.
I am attempting to get a very simple program running on
rpy2-2.0.1.win32-py2.5 without success.
I am trying to save a simple plot
--------------------------------------------------
import rpy2.robjects as robjects
r = robjects.r
x = [1,2,3]
y = [2,4,2]
r.png('plot.png',width=500,height=400)
r.plot(x,y)
--------------------------------------------------
The program executes fine without error,
but the file is empty without data, file size = 0KB
If I take out this line of code
r.png('plot.png',width=500,height=400)
the program works fine, and the window pops up with my graph.
Also,
r.dev_off()
does not work in RPy2
Do I still need to use this function ?
It appears, I don't need it, because no window pops up with the above
program,
when I am attempting to save a graph to a png file.
If I do need
r.dev_off()
What is the proper syntax to get this to work ?
Thanks,
