if you don't need to exchange big data between r and python, pyper might be
better than rpy2.

I don't believe that rpy2 will load a saved workspace. When I have worked
with this I always load my functions by sourcing an r file separately:
R.r['source'](MyFuncs.r)

Solve:
I wrote the buzz function to buzz.R
And now I have:
from rpy2.robjects.packages import SignatureTranslatedAnonymousPackage as
STAP
with open("buzz.R","r") as f:
string = '''.join(f.readlines())
buzz = STAP(string,"buzz")
buzz.buzz(3)
And all is well!
Thanks,

Erin, one question, can you access the defined functions by key?
In lieu of:

Can you do:
x = R.r['buzz'](3)
Alternatively if you need only one or two custom functions have you
considered just defining them via python as in:
PStr = """
function(LM) {
S <- summary(LM);
pr
Could you produce a full working example then? Bit hard to debug without
knowing what you did.

Presumably you need to define 'buzz' first, but I don't see evidence that
you've done so.

Hello again!
I'm using python with a module rpy2 to call functions from R.
It works fine on built in R functions like rnorm.
However, I would like to access user-defined functions as well. For those
of you who use this, I have:
import rpy2.robjects as R
x = R.r.buzz(3)
