|fixed Rmagic in IPython Notebook||erin clausing||6/18/13 9:10 PM|
I finally got Rmagic to work. One might be able to skip to step 5 if you have rpy2 working in Ipython but are still having problems with Rmagic. It appears to be working correctly although the cell showing the [correct] results of the %R cell is unusually large for some reason. Haven't tracked down why yet. If you have any ideas, please let me know.
1. I installed Python(x,y)-220.127.116.11.exe
2. I had already installed R-2.15.3-win.exe
3. I installed Rtools. Exact filename: Rtools30.exe
4. I installed rpy2-2.3.0dev.win32-py2.7.exe which I got from
following the instructions here for setting up Rhome, Ruser, and path variable changes
I tried the regular non dev version of rpy2 but it didn't work for me.
5. Then I went to my IPython extention folder which for me is: C:\Python27\Lib\site-packages\IPython\extensions
and opened rmagic.py for editing. Found the line
Supposedly this issue was fixed. See here:
So I'm not quite sure why my Rmagic.py still had the problem.
6. Put %load_ext rmagic in first cell and run it before trying %R
Hope this helps someone,

Has it something to do with following issues?
Blank figure appears in output:
And for those who don't want to build RPy2 yourself, Christophe Gohlke also provides binaries: http://www.lfd.uci.edu/~gohlke/pythonlibs/ (which worked for me).

Thank you SO MUCH!!!! I have spent way too many hours trying to fix this problem so I was just going to live with manually resizing the empty image to a tiny size for a while.
Going into rmagc.py and using your line fixed my problem:
If I use the %R as in the following example, I get output:
array([ 1., 2., 3.])
If I use the %%R, I get no output (I do get the output in the console) :
x <- c(0,1,2,3,4)
y <- c(1,1,1,1,1)
z = x + y
However I can get the output using a %R in the next cell
array([ 1., 2., 3., 4., 5.])
I can also do this to get the output:
[ 1. 2. 3. 4. 5.]
This link seems to imply that a block of R code won't bring anything back by default:
